Making Simple Linux Distro from Scratch

[@nirlichtman]

- Note that if you don't get the bzImage is ready message when make finishes, it may be that the build failed, try running make without the -j flag, this can help you see the error more clearly (if you use -j it can cause the error message from the build to get mixed with the output coming from the other build threads which can be confusing since you need to scroll up until you see the error)

I have run Linux since kernel 0.99 (Slackware on floppies) and never really knew/thought about the individual bits and pieces that make up a Linux system. This is super educational. I would love to see an expanded version of this that allows for a basic Linux distro (that includes everything that you mention it would need for production) but without any of the bloat that normally comes with distros. A tiny server Linux if you will. Also, just in general, thank you for making these videos - they're awesome! I appreciate the time and effort you put into them.

[@xcoder1122]

Instead of dd if=/dev/zero of=boot bs=1M count=50 you can also use truncate -s 50M boot truncate changes the size of a file. If the file does not yet exist, truncate creates it. If the size is shorter than it used to be, the file is in fact just "truncated", hence the name. Yet if the size is bigger, zeros are added at the end until the file reaches the desired new size. Not only is the command shorter, it also has another advantage: truncate creates a sparse file on systems that support that. That may not matter in this example but it would matter if the file was 100 GB in size. In a sparse file, only blocks of that file that contain actual data also use real disk space. All blocks that are still zero filled are virtual, they don't use any disk space and they are also not actually created when you created the file, so file creation is also ultra fast, as all that really happens is that a directory entry is created for that file. Yet when the file is accessed, it will always behave to any file operation as if the file really was 100 GB in size and all filled with zeros. If you jump to the middle of the file and write some data there, only blocks covered by that data will materialize and actually consume disk space, the rest of the file stays virtual.

Hello. If I understood correclty the ramfs is indeed for syslinux. The kernel will mount the cpio archive pointed out by syslinux to the kernel through the command linux. I remember It is also possible to embbed the cpio inside the bzImage itself (option in menuconfig).

[@TaschenRechner22]

Great tutorial Nir! I have a few followup questions. 1) You used the default kernel config file that came with the repo, instead of replacing it with your Ubuntu machine's config file. And in the default config file, the only change you made was enabling 64 bit. Would that cause any issues if you were to use this kernel in production, since it wasn't "handcrafted" for your machine? 2) Why don't you have to run 'make modules' after you make the kernel? Does the default config file just set all modules to be compiled into the kernel? 3) If you set some modules in the config file to be compiled external from the kernel, where would we copy those .ko module binaries so the kernel could use them? Would they need to be copied into the initramfs cpio archive? Or would they need to be placed on a real disk in a root filesystem the kernel would switch to after it goes through initramfs? 4) Since you copied BusyBox directly into the initramfs archive, the kernel didn't need to mount any real root file system on a real disk. However, suppose we did want to use a real root fs on a real disk, and install BusyBox there instead. How would we need to change the init program and initramfs directory structure and content to make the kernel mount the real disk and change the root directory to the one on the disk?

[@nirlichtman]

It is as extendable as any other distro except that you need to manually bring over the package binaries for every tool you use (or manage to get some package manager running). To make it actually usable for day to day you would probably also want to setup proper tty devices, init (and not just start the shell right away like i do in the vid - busybox also includes init built in but I didn't use it in this video) and a persistent file system to start after the initramfs

So I've tried doing this on my M1 mac and spent an hour swearing and cussing ;-) So the problem is the arm architecture (even the menuconfig is different). It creates a slightly differnt image (Image.gz) etc. And the worst problem is the bootloader. Syslinux doesn't exist there (but there is some syslinux-common package). If you could suggest some workarounds, it'd be great. Tried playing with u-boot, but since I have very little experience with bootloaders, I didn't make much progress. In the end I emulated the right architecture (docker run --platform linux/amd64) and I'm doing it from scratch again. However it's visibly slower. On original architecture, the kernel compiled in 8 minutes. Now I'm way past it and it's still compiling

Shouldn't be a problem, you can also boot this on a real computer, it is a bootable disk image

[@sabirrajabov]

I have a custom built distro without boot configuration. So based on this tutorial, i did convert my whole root directory into init.cpio (init script also added). And did the same boot configuration(based on distro size, i have created the boot file with count=4000 (4GB)). But when i want to run the kernel via qemu, "init.cpio...failed, no such file or directory" error occures. Does anyone have a idea? The cpio file exist i had double check.

If I want to use the default init from the busybox instead of the simple bash you provide, what should I prepare?

LFS will guide you :)

[@_lun4r_]

Just compile busybox with it and "ln -s sbin/init init" so the kernel can use it

[@AlexChen-bu2de]

Slackware installer is my ideal distro 😂

[@tonywmckinney]

Anyone know why I'm getting this on the "mount boot m" step? Tried ubuntu and Debian containers.

[@tonywmckinney]

Never mind. Turns out it was a Docker issue. Once I updated Docker, it works.

[@NaomiUsman]

Great video! Been trying to replicate on my own. I use a MacOS and I am using Multipass VM will it work the same way?

[@nirlichtman]

Thanks! I don't know Multipass but from what I understand it helps bring up Ubuntu virtual machine, so shouldn't be a problem. Only thing is that to run QEMU you'll probably want graphics so you might want to run QEMU natively on the Mac if Multipass is CLI only. (you can also technically run QEMU without graphics by passing -nographic and a serial tty option to the kernel command line)

[@NaomiUsman]

@@nirlichtman Thank you for the response! I'd try this and come back to let you know if it works.

[@stevenchristenson2428]

I had to do somth9ing very similar before to be able to boot systemd system when using a btrfs file system. I however did not use busybox as I did not need a full enviroment to work in. The system basically just needed to load up enough system to be able to read the file system and start systemd, then pivot root into the real FS. Funny enough what you did is pretty much what dracut and other programs are actually doing when they create the initramfs image.

[@k.r.3821]

It would be nice to start with Docker installation. Not everybody knows what it is.

[@silme9417]

I love your video, can you make one on how to make http request for windows os?

[@nirlichtman]

Yes, I plan on covering some winsock related stuff as well :)

[@FuniCatreal]

Thats cool! But yet, how can i add like, packages to it? Like, some GUI of sort? Or, python?

[@nirlichtman]

One option is to compile them from source and transfer the files, I have another related video of making a graphical distro in which I demonstrate compilation of another project called MicroWindows which provides a graphical interface (but I don't have a video about setting up X11/Wayland yet). Another option is to try setting up a package manager.

[@FuniCatreal]

@@nirlichtman nevermind, microwindows already supports x11, and thats what i need!

[@nirlichtman]

@@FuniCatreal sort of supports but not really since you need to recompile x11 programs to be able to run them on microwindows. Also, in many cases it can happen that programs use specific x11 features/functions that microwindows does not support. still would recommend taking a look at microwindows since it is an interesting project

[@tarksapmaz7690]

As far as I can see, you do not have a training video series on these areas here or somewhere like udemy, do you have a plan for this in the future? You have very good information and your narrative style is very clear and clean.

[@Reelix]

MFW your x64 kernel compiles into the arch/x86 folder ._.

[@reyuki-i]

6:15 Ahh, it confuses me, much like the chicken and egg situation 😅

[@nirlichtman]

Are you talking about the fact that I used the shell to start the shell? I am just running the shell and the first command the shell is going to run is the shell :)

[@CEOofGameDev]

Oh, yes, my dream is now one step closer to being realized. Soon enough you all shall tremble before the power of my own linux distro, liNUTS.

[@kobodrago2758]

I am gonna try once i get some time to spare. Really interesting. Can we make a distro with AI integration ?

[@PAFBEAST]

Great question

[@fabrilluviaofficial]

boot is not an "*.img" file. help please!

[@nirlichtman]

Where do you get this error?

[@fabrilluviaofficial]

​@@nirlichtmanjust before you open a new cmd tab to mount it with docker, I open on file explorer (because I use wsl), and it says "archive", I open it, and don't have extension! if I change the extension, to img and iso, vmware says "no operative system founded", and when I change it to iso, I cant mount it!

[@fabrilluviaofficial]

@@nirlichtman i get it just before of mount it with docker, I have tried to change file extension, img = doesn't work at vmware, iso = doesn't mounts, and it doesn't work at vmware

[@justinnamilee]

hmm... simple panic fix would be while [ 1 ]; do /bin/sh; done? xD At any rate fun stuff, I used to do LFS for fun when I was a teen, makes me miss those days.

[@sarkar2320]

Hey I have a project as a part of my OS Course called "Linux Kernel Development". Can i make this as my project. Or kernel development is far more beyond what you did in the video?

[@nirlichtman]

Depends on the project criterions, on this video I did not make any modifications in the kernel code but mostly worked with it as a whole component, I have a video about adding a simple system call to the kernel, that may be more relevant. Another option is my video about making a simple kernel module.

[@getvasanth]

Happy to see this!!😃

[@f2pgamer39]

How do u use dwm on windows??? Really confused 🤔

[@nirlichtman]

This is dwm-win32 (a port for Windows), due to bugs and stability issues, I have since decided to start writing a new twm from scratch and moved to using it instead (LightWM)
