You lost me at flatpak - I don't see a use for something that the OS cannot see is installed. It's how viruses wants to be installed - with the OS completely oblivious to it. I dislike how integrated it is in SteamOS and how you cannot launch the lutris from command-line.

I've been using NixOS for the past 8 months or so. It's completely changed how I manage my system. Everything has a learning curve, but once you get past it the rewards never stop flowing.

[@fizipcfx]

i have a question does nixos being non-FSH compliant makes anything impossible or harder for you? I heard that this is a deal breaker for some people

[@bstar777777]

@@fizipcfx It's not a problem for me because I have 2 fallbacks... steam-run and Distrobox. This has solved 100% of software/scripts that don't run out of the box on Nix.

[@aemogie]

​​@@fizipcfxpersonally faced no issues as just about everything I need is on nixpkgs. but if you have a binary that requires FHS, nixos has a builder function that just wraps a package in an FHS environment, which is the recommended way (this is how the official package for steam, android-studio works) but if you want to add back some DLLs system-wide, there's nix-ld. it just adds support for dynamic libraries the way it's done in regular distros (with the version incompatibilities and all, that nix is trying to solve. i recommend using it but keeping it to a minimum)

[@fizipcfx]

I am going to answer my own question because i had used nixos for a while now. Most of the generalized stuff works out of the box without much intervention thats very nice but, development almost always get in my way. (Python c++ cuda) Either do everything inside docker, or you are gonna have to let the nix define the way you work. I have installed it on my laptop that i carry everywhere but i dont see it being my main development setup. I had to deal with these: - install every tmux extension through nixpkgs - install every python package through nixpkgs - forget using pyenv - migrate almost all of the dotfiles so that it is compatible with nix ecosystem - rollback is nice but it doesnt rollback your configuration so if you did so many successive changes without rebooting you dont really know which one messed up the system - nvidia support is ass Regardless, it was a fun learning experience.

I've been using NixOS for a year now. It's great but the main problem for me it's the lack of documentation in some parts of the project. Btw, using flakes (which are unstable but have been unastable for quite a few years) is really a game changer. Makes everything easier to configure and to manage in your daily chores.

Anyway, I wish you the best Nix-journey possible and will be following your adventure. Have fun and thank you for sharing those great videos with us :)

[@kr8771]

I am in awe to see this magnificent distro receiving so much appreciation. Thank you very much for your contribution in making NixOS more beginner friendly. I greatly appreciate it!

[@10a3asd]

Many many years ago when I was first planning my move to Linux I researched a ton of distros. Based on my criteria and what I wanted from an OS NixOS was by far the winner. However, at the time I was severely lacking in technical acumen. As a result I ended up on Mint. After years of Mint I moved to Kubuntu, then KDENeon, all were less than great experiences... Finally two years ago I moved to Nix. It's so damn good and they have made huge improvements in the areas that made it previously overly technical to many users.

[@merbst]

(Note Bene, the following is not a brag, more like a "heh" is the proper noise if I were capable of majing it. Actually today is my 42nd birthday, which is too old to do anything.) I remember when I switched to Linux, I used Slackware on 3.5" floppies, because that was the only extant distro in 1997.

Good to know! I started down the "normal" Linux path like everyone else, distros years ago (and still, sometimes) then a year ago Arch with Window Manager, been running Arch + Hyprland for about 4 months now as my daily and love it. But I keep hearing/reading about Nixos more and more recently. Obviously jumping into something new there will be the learning curve but based on how you explained your experience, I am encouraged. I think I will check it out, thanks for the comment.

[@stalkerscarface]

Documentation should still be better, bigger and much more specific, I tried it few months ago and I couldn't figure out how to install nvidia drivers, I believe I followed their documentation step by step exacly, tried tinkering on my own, still couldn't get it to work.

I've been waiting for something like this for years (decades actually). I deliberately avoid doing any config to my linux systems and I use the easiest plain vanilla linux I can because it's a deadly rabbit hole of confusion and breakiness trying to customize a system. The NixOS one-off virtualization scheme is freaking brilliant and long overdue. THANKS FOR THIS!!!!

[@christophstich5066]

Changing your config on NixOS is still a rabbit hole but at least you are highly unlikely to break anything. Out of the probably thousands of changes only once ever broke something that I couldn't just roll back.

[@thecandyman9308]

So, I'm a bit dense, but are you saying that w/ Nix, it's sort of running an "instance" of what he's specifying in the config screen in the video, almost like the OS is a hyperviser host and you're operating in an isolated "sandbox"? As compared to a more traditional distro where you're running in an "all-encompassing/all-in-one" OS?

[@bobbyv3]

You're not the targeted audience for Linux, my friend. If you're afraid of configurations, just stick to Windows.

[@deathgripsonline]

Chris, Discovered your channel a long time ago starting as an amateur hobbyist. Enrolled in college and have tried to completely immerse myself in the computer world. I even emailed you once about audio mixer configurations. I'm just about done with a bachelor's in cybersecurity and information assurance. Working on the SSCP certification exam right now, I have SEC+, A+, Net+, project management certified.. trying to crunch all of that before 30. I watch your videos even if they aren't relevant to what I'm studying because I am fascinated by everything. I want to become a tech priest, basically (joke, not literal lol). Blue-collar upbringing, etc. I have never installed a Linux distribution by myself, only in labs, and I have been too nervous/not confident in installing by myself. This video with the "$300k salary" made my ears perk up. I will have to tackle this. If you were starting again today, fresh out of school in 2023, what would you say to yourself? Thanks, -Ted.

[@esaedvik]

It's a fun hole to jump into, learned a ton and tried to make myself some random notes on how to do certain things, but got a job JUST after I plunged myself into one distro and tested stuff on it. Now a lot of that knowledge has been replaced by my new job and stress :D I bought an old "1 liter" HP Elitedesk to use as a "lab" for installing stuff like Proxmox, Unraid, OPNsense etc. Super cheap way to get into the swing of things, paid 150-ish bucks for it and it's not too shabby, i5-8600T, 8GB (32GB max), 250GB M.2 NVMe SSD (two slots), 10Gbit USB-C, 2 DPs, one HDMI etc. Nice value and if you have more to spend, there's a ton of them around cause companies lease them for 2-3 years and sell off cheap.

[@anmol3457]

[@hydroponicgard]

I don't think I'd ever use NixOS as daily driver, but as a rather mass deployment "device" (per see), which would be GODLY for data centers and blade servers running similar/same things. Great video, CTT! :D

I tried to use NixOS a few weeks ago, but wanted to use flakes and home manager to do things, having separate branches for my desktop and laptop configs which could be chosen by using a single command. I wound up getting frustrated and quit because it seemed like everyone was doing different things and finding answers to my questions was a pain.

Since Nix is its own language kinda - There's often multiple ways to solve the same problem. Just like programming. Pick the way that appeals to you most.

[@skirnir393]

I started using Linux back in 2007 and did my share of distro hopping, yet i never heard about NixOS back then. I think it is because i didn't have a broadband internet connection and I used to buy IT magazines that included Linux CD-ROMs and DVD's. Finally I settled with Ubuntu because it worked fine on my Thinkpad and that's what I've being using since.

[@sully-kg]

I've been using NixOS for a few months and I love how stable it is but if you don't need supreme reproducibility I find it pretty overkill. I enjoy tinkering with it so I don't mind but I've lost count of the times I've thought "I could solve this in 10 seconds on Ubuntu" while trying to nixify a config or just get a program working the way I'd expect (NordVPN is especially brutal imo). That said the massive package list helps keep me here. I'd love to see a couple of videos about flakes and HM, I just changed my config over to them a few weeks ago and while it made some things much easier I do kinda miss the simplicity of using 1 configuration.nix for nearly everything.

[@woobilicious.]

When you go to do a major distro update in a year you'll be thanking that you configured it using NixOS and not a bunch of ad-hoc configs that break when software is updated. updates in Arch or Ubuntu was always a PITA if you had used software from AUR or other 3rd parties and dependencies changed. I ran a patched kernel and it automatically applies my patch to nixpkgs upstream kernel version, and it keeps the old kernel around for if anything goes wrong during boot.

Just started down the nix rabbit hole. Got it installed in a vm on proxmox and used it to build a nix os pi image. Its about a 80 percent solution but I'm already a huge fan of this distro. Thanks for the videos on it, it has b3en a huge help for the steep learning curve it has!

[@etherweb6796]

Ive looked a NixOS twice. The second time I tried it, I was happily generating my system config and realized you cant install the amdgpu-pro without quite a bit of hassle. This is a showstopper for me - I realized that the problem with NixOS is there are too many configuration options for all the open source projects out there, so there will always be a game of catch up on the part of Nix developers and users. A great idea in theory, but it really needs an opinionated set of core software and to direct the users to use that software if they want it easily configured.

[@whyredfire]

I won't install it as my host OS for now but would try to learn it in docker for sure. As someone said below, it would be really taxing to rebuild the whole system every time. This is good for a particular use case, like settings up dozens of machines with the same configuration.

[@quasigod1083]

The entire system isn't rebuilt. Everything you build is saved in the Nix store and reused. Most packages are also pulled from a global cache.

Having everything in one config file is wonderful. That’s always been an issue finding where everything is in every slightly different distros

[@maxarendorff6521]

NixOS can be awesome but the documentation is lacking and some apps don't work right with its non-standard file structure and you just want to pull your hair out getting stuff to work. I used it for while on the desktop but I ended up switching back to Fedora because configuring Neovim right was a huge headache on NixOS. I still use NixOS as a server OS on my NAS and other machines and that's where it really shines. It's so easy to configure and automate things and you can even configure docker containers with it. If there is a hardware issue, no problem just reinstall the OS, copy over your config file, rebuild the whole system and everything just works.

[@coffee-is-power]

configuring neovim on nix os is not that hard, i managed to make it install lunarvim automatically, which is a really big configuration that turns neovim into a full blown IDE. I basically did that creating a custom package.

[@PenguinRevolution]

Nix OS has always interested my and I think it's great for deploying on a fleet of computers if you want the same configuration on every computer. It's a well done project. Also congrats on reaching 500k subs.

Been playing with NixOS and I like it. BUT, I have discovered they have zero tracking or facilities for handling security issues and updates. There is no one tracking what security issues exist, what needs to be updated etc, its totally up to whoever to updates the individual nix software packages whenever they feel like it.

[@0netom]

I'm a Nix (shell.nix) user on macOS for Clojure development, for ~5 years by now. I did use NixOS too a couple of times on real hardware too. No more lengthy installation notes in READMEs to follow (for most software)! It's just faaaantastic! I still install my GUI apps with `brew install --cask` though.

[@GeorgijTovarsen]

I have just moved to Nixos and I am having an hard time with some services that are not there in the repo, it is very difficult to understand what the code behind it is actually do it, the language itself is easy but many time it is not evident how expression are evaluated how they translate to the actual configuration. In my case I have a program that takes a configuration file as input and it is supposed to run in background. The program is that I don't know how to write the configuration to a file on the immutable filesystem and how to pack the command into a systemd service. Everything in NixOS seems ready to be used, but as soon as you have to do things "manually", it really takes a lot of time to research as the documentation is not really easy to grasp

[@yzxc222]

Chris, I saw that you have packages from flatpack and nix-os on your system. So I have a question: if you need to download a package and it's available in both nix and flatpack, which one would you choose and why?

[@vaisakh_km]

i never used nix, but i guess we need to go with officially supported one.. and mostly it would be flatpak.. so if there any errors, we could easly report but then again, i guess it will hurt reproducibility of the build

[@whyredfire]

I personally always use flatpak packages for all the GUI apps I have, love the modularity.

[@ChrisTitusTech]

Depends on what the end goal is. I find flatpak does a better job of sandboxing it... Discord for example is something I don't want having access to my files on my system. Very easy to lock it down, and still use the program. If this isn't a concern I find nix packages a bit faster than flatpak and would use it for something I want everywhere... for example neovim a text editor I use.

So a request to the community: What is the path to utilizing this kind of configurability? I am using Mint because I just couldn't STAND Windows anymore. (Even with Chris' tools I could never seem to get away from telemetry and updates overwriting my preferences.) Since installing Mint I have used it for routine tasks like web browsing and word processing. I know this must sound completely lame but I was a ham and egg Windows/NT networks sysadmin for a few years then transitioned into human services ten years ago; I want to learn how to use this system. I was never into bleeding edge and I never subscribed to tech magazines - I just managed desktops and LAN and CRM at a small software company. Every time I try to engage with Linux I just get frustrated and fall back into standard tasks.

[@abhinavlakhani5637]

I have heard about nixos b4 that it's really good for maintenance, security and configuration. Though, I would be interested to see the heights of automations that can be done in nixos which sets it apart from other distro. Also, I use Manjaro like an Arch user. I use Hyprland btw.

[@ppen9u1n]

What sets it apart is that it's "config as code" all the way, meaning that everything you'd do on another distro by clicking, pointing, selecting, editing configs and what not *on every machine* manually, you do once in your (ideally version controlled) nix config. That means that even if it's a steep learning curve, you'll never need to do the same task more than once. And that's just the start, you can also build logic in your system declarations that makes settings depend on eachother, or the device architecture, etc.

[@volchonokilliR]

Thanks to this video, I've tried Linux for the first time, and now migrated to it. Everything in NixOS worked straight out of the box, and although in the end I still needed to do a lot of configuration and figuring out, it is easier to set up lagless and optimized system than on Windows. Much less work and arcane knowledge required. And result? I have a more stable, prettier and better working system!

[@volchonokilliR]

One of the biggest things to pay attention which want to mention though - I had limited color range set by default on Intel videocard. On X11 with KDE for some reason there is no option for this in System Settings. Curiously enough, this option exists when using Wayland. But Wayland is not ready for serious gaming yet. So, the program to know if you have limited color range is "xrandr --verbose". You will find you display there and line saying "Broadcast RGB" (this is for Intel cards). By default I had it at "Limited 16:235" (which is obviously not good). The way I figured out to change it, is to execute xrandr command when display manager starts each time when you load your system. I've done it from configuration.nix in the following way: services.xserver.displayManager.setupCommands = '' ${pkgs.xorg.xrandr}/bin/xrandr --output --set 'Broadcast RGB' 'Full' '';

[@volchonokilliR]

in the same way, it is also possible to for example, overclock your monitor. My monitor has only 60 Hz modes officially integrated, but is actually capable of 75 Hz. I was able to do so on Windows with NVIDIA card. Unfortunately, either because of Intel card or different OS, right now I can only do 73 Hz otherwise it is messed up, but at least it's not 60 Hz.

[@sgr_sgr]

Wow! Thanks for your time & effort putting all this together. I’m going in!

[@pajeetsingh]

Gentoo is so much better than Nix configuration thing.

[@samsh0-q3a]

I've been eyeballing NixOS but ive been comfortable in Debian for so long.. IM AFRAID OF CHANGE 😅 ill look at it eventually lol

[@danwake4431]

i feel the same. im so freakin happy with MX Linux and xfce. people talk about nix being so stable but i dont have any problems with mx. so its like, what else ya got? lol. i play with manjaro, mint, fedora, and pop on my other boxes for fun but i could format those drives and not shed a tear. ill probably delete mint at some point and try nix i just dont know why.

[@ppen9u1n]

​@@danwake4431 considering MX is so stable in the sense of "very slowly changing", that's a fair point. The stability of nix(os) is praised because it is stability "in the face of rapid change", which is arguably a different use case. But I also like to think of it as a "configuration effort insurance", meaning with NixOS I know that I never have to painstakingly configure my system again (not even remember which apps I want installed), whatever happens.

[@momomaniac1234]

well done Chris 👏🏻👏🏻👏🏻👏🏻

[@gwgux]

Funny, suddenly today, I'm seeing videos about NixOS suddenly show up on YT. NixOS has been around since before Ubuntu but it's always been that quiet one in the back of the room kind of distro for me with the louder ones, Arch, Fedora, Debian, Ubuntu, etc., having the main focus. Definitely time I finally take a look at this one.

[@danwake4431]

same for me. today half my recommended videos are about nix and i had never heard of it before, certainly never searched for it. did they pay for that or what lol

[@ChrisTitusTech]

I have been streaming it for 2 week straight and talking about it on twitter. I guess everyone decided today was the day to put a video out about it. I only looked at it because of the job offer I received last month.

[@shambali293]

Add "apx" to your Nixos config for everything that isn't already in the nix repository (which is admittedly huge).

[@rursus8354]

I think this OS is historically important. Linux sysadmins, as well as programmers will prefer this OS, once they become acknowledged with it.

[@dljohnsonmusic]

This seems pretty awesome....I can't wait to do a deep dive using the items you provided 🙌

[@longlost8424]

as usual chris, another amazing tutorial for both noob and advanced.....

[@chrisallen6010]

Looks like a nice configuration management built into the OS like Puppet or Chef. Reminds me of the 'gitlab-ctl reconfigure' command.

[@SMOKE3104]

I tried using it once before and absolutely love it. I love having everything managed in a single file (if you want to), my issue came when trying to install things that are tricky to install on, let's say, pop os or arch. I keep looking for reasons to go back, I just need to know a bit more on how it works.

[@benjy288]

I ran it for a while about a year ago, I can't remember why I went back to tumbleweed, probably because I wanted a rolling release again, but I just switch back to nixos a few days ago after realizing I could just run the unstable branch as a rolling release, so I got stable installed and sorted, then I switched to unstable, and now I can choose to boot either stable and unstable, I don't know of any other distro that can do that, and if something eventually breaks on unstable I can just boot back into either another working unstable generation, or boot back into stable, its kind of like having btrfs snapshots without having to run btrfs, I can't see myself moving to another distro ever again.

[@ottolehikoinen6193]

Ok. Absolutely one to try out if you are planning to become an it-professional. Not quite Arch, but before diving into some deep level OS stuff. Intermediate difficulty.

[@rabidrivas]

I have two questions: Do you plan to daily drive this? Can you link the job postings?

[@ChrisTitusTech]

I have been for 3 months and used indeed for the job postings. The 300k offer was sent personally to my email and not a public posting. Just used indeed.com and Nixos as search term to get a baseline. Which is normal anything over 200k typically is privately handled by recruiters since they get a percentage of the salary if the hire goes past 90 days. Different type of hiring procedure when you get in to that realm.

[@flirtypie]

An app that makes a config file for nix os would be nice. Like the debloater you have for windows, just for nixos before install.

[@andrewferguson6901]

Gcc can do it

[@andresandrek88]

Thanks Chris for you educational videos! much apreciate all your work. kind regards from Argentina

[@triffy3402]

I'm really like your Channel that's make me challenge for me to change from windows to Linux and I like it open world , do you think nixos is good for gaming and programing??

[@ChrisTitusTech]

Any distro can be good, but Nix will require quite a bit of configuration. I wouldn't recommend it, because for would need also need to build out shells for your programming as well. Lots of work where I'm a bit lazy and prefer just debian for most of my programming.

[@Ski4974]

NixOS is good for programming because you can easily craft dev environments with the right dependencies in a reproducible manner. See direnv and devenv projects.

[@mbrock5532]

Very cool! I'd seen this off and on but never really investigated it. Sounds fascinating.

[@Immortus27]

Looks great an kinda stable. Would you recommend this for work? You've said a lot of good things about this distro, but also it would be as useful to know what problems did you have(or not) at the start and how easy or hard it might be to move to this distro

[@ppen9u1n]

Yes, definitely highly recommended for work, but for a beginner you should factor in some learning time reserve. If you can't get a certain exotic app (e.g. downloaded binary or game) running quickly enough, you could try with steamrun or in a container to avoid having to troubleshoot. This type of issue is the most time consuming, others are pretty benign. On the long term you'll earn back your invested time because you never have to redo significant configuration tasks, not even when migrating or duplicating systems. (Just copy and modify the existing config and rebuild).

[@foreignconta]

I wonder if NixOs will be suitable for my daily driving. I need KDE plasma desktop with sddm-git, pytorch with rocm enabled, firefox browser and flatpak. Will checkout sometime later this year or the next year when plasma 6 will be released. The hard block is the sddm-git which I prefer to run on wayland instead of the usual rooted xorg with plasma 5. Auto upgrade caught my attention the most. Arch does well with chaotic-aur repo. As you said , since there is very less documentation on this I was skeptical to switch to it since long time.

[@agh0x01]

At 07:39, actually NixOS won't build something it has already built unless the inputs change, so if you didn't touch your dwm build, there will be no extra compilation, etc. The version already built and in the Nix store will be used.

[@RobFisherUK]

I'm intrigued. One problem I have with my computers at home is they tend to accumulate cruft as I solve problems, and I forget what I've done. I've tried putting config files in Git and so on but it takes discipline. It seems as if nixOS might have the answer to that.

[@esaedvik]

This was pretty much my reaction to Pop!_OS a year ago when I first tested it. Thoroughly impressed and couldn't break it throwing all the random shit I could find at it. Plus it was running on 10-year-old hardware. Nothing SUPER special in general terms, just the fact that I got it to work as well as it did and still does, on two PCs now, was good enough. Two more to upgrade from W10 :D Really didn't have to do much more than just google a ton of stuff since I'm not super fluent in Linux, I just dabble. The only thing I couldn't get to work or find instructions for, was streaming video on Discord, which I heard is now fixed for the most part by a third party.

[@omni4376]

Interesting package system. Someone should tell those guys about containers.

[@TheOne-ok7gn]

I tried it 2 times before , both unsuccessful the amount of time needed to learn the language is beyond me. i don't have that much time. One of my problems was i couldn't open specific appimages on nix. i suspect some of runtime dependencies were not universally available . now i hope i can go for a 3rd dive using your tutorial.

[@_taylor_v]

Great video! Are you recording this on a NixOS machine? Or is this some kind of VM?

[@endermanofficial]

just remember: as the rate of consolidation increases so does the corruption. Consolidation centralizes power and the bad actors are attracted to it like a moth to a flame. Segregation, compartmentalization and isolation is important

[@rursus8354]

Sounds profound, but it is probably not true. Debian. Not corrupted. Corruption is probably due to the lack of democracy, and the ability for bad persons to rise where there is no scrutiny of their behavior.

[@endermanofficial]

@@rursus8354 so sjw activism is supposed to be a FIX? um.... no. democracy is the majority rule, so that's another big no from me. I can assure you though: I am correct in my assertions and you will come to understand this, one way or another. i hope it doesn't cost you too dearly in the meantime

[@davidprock904]

Thank You, Thank You, Thank You Very much!

[@mrwhitebp]

So are we going in circles? We were trying to make things more modular , I am wondering what is going to happen if that file gets corrupted and a user doesn’t have a backup.

[@peachy7776]

obviously rule number 1 is back up and version this file

[@vlya1533]

It would be nice to make a review comparing nixos and guixos

[@knightwolf8877]

Yes finally love the concepts going to install this tomorrow

[@_modiX]

You are doing a huge service, I want to dig into NixOS, because there are hardware configurations for my MacBookPro16,1 (T2 chip) available. Trying to free myself from macOS on this brilliant hardware.

[@fontenbleau]

It's not brilliant at all 😂 believe me. As owner of two Macbooks Pro I advice you to get cheap additional Intel laptop, Apple really engineering obsolescence, thats why forums filled with mass complaints how Amd graphics dying in Macbooks right after warranty period. And that was normal computers where everything not glued & soldered together into big e-waste. That Arm chips Macbooks are basically iPads in alu shells, where not only graphics but SSD planned to fail from overheating, I hope Apple will be bankrupt.

[@_modiX]

@@fontenbleau T2, not M2 ;) It's the MacBook Pro 2020 with the Intel chip. It's the 2nd last model before the M1 came. It is the one without the final GPU upgrade (which was 16,4 - it's still powerful though, great for gaming in BOOTCAMP) and there are NixOS Kernel patches for my model available, and lucky me, the 16,4 GPU upgrade is not compatible with those patches. I probably have the last MacBook that will have medium to high hardware support, but it's already rough, because things like dynamic switching between integrated and dedicated graphics won't work (I will have to reboot for that). I still love the quality and feeling of Apple's hardware, but you are right that it is garbage in the long run, unless I manage to get it to work, as well as the community will keep working on it. It's a T2 Intel chip after all, so the support will probably bump in a few years when macOS feature updates will be canceled for this model. Honestly, give it time. ARM Linux is on the rise, too.

[@fontenbleau]

@@_modiX they made planned obsolescence 10 years ago, it's present in yours too and as Louis rossman said such Macbooks from 2020s are not repairable

[@_modiX]

@@fontenbleau actually I followed him closely before buying this. This is the last model before the M1 that did things better in Rossmanns own words. However he still recommend against getting it, as the power line is exceptionally close to the low voltage data line on the motherboard. The rest seems to be fine, but yea, repairability is shtt, I know right. I'm looking forward into tapping my hands into Linux to find ways to get things done without Mac software. Especially the reliability in iOS publishing must be given, but maybe a Mac Mini in the cloud would be a better option. I can't go for Windows, so macOS was always beneficial, because of the stability of the OS and the unix foundation make it a good OS. This is business not hobby in my case, so you might understand where I am coming from.

[@mc-not_escher]

I’m on a Manjaro system at the moment. Running Plasma Wayland with a btrfs disk and I am failing to see why NixOS is *that* good otherwise from a deployment standpoint (which doesn’t make any difference to me whatsoever with a single system under my administration). Maybe if I were imaging lots of stations I could agree, but perhaps I’m just missing the point here. Looks slick enough though.

[@adrianscarlett]

I just installed it, replacing arch. You're not kidding, it really is mindblowing. My only complaint for now is that the live image makes you go through disk partitioning during setup. I was hoping to do all my configuration on the usb image, then burn it to the hardware when i was ready.

[@JohnDoe-lg8zt]

Yet another layer between the user and the system. On paper, it's enticing to centralize everything into one configuration file and let the magic handle the rest. I tested NixOS and quickly reverted back to Debian and Ansible. In certain situations, you end up being hindered by its rigidity and the documentation is subpar. It's worth investing time in understanding a GNU/Linux system and scripting appropriately for automation.

[@_boux]

I always wondered why linux package managers didn't support version targetting to avoid dependency hell where upgrading a library can potentially blow everything up, maybe I should give NixOS a try

[@andham95]

Nixpkgs is more similar to other package managers than you might expect, in that regard. Out of the box you can not upgrade a single package, you can only upgrade your entire system. The nixpkgs repo mostly has a single version of any given package at any given time - though for major packages or language runtimes (like node or ruby) it's common to have distinct packages for different major versions. Pinning a single package from an older version of nixpkgs is certainly possible, and works pretty well, but it's a bit advanced, and has its drawbacks. For example, an old package will use an old version of OpenSSL, no matter what. Nix more or less forces all dynamic linking to be "static".

[@nmac101]

Finally I found the perfect os. My long journey was Ubuntu > Kubuntu > Xubuntu > Linux Mint > Debian > Arch Linux > NixOS
