i think, you have missed one step.. when you enter into rescue mode, system loads under "/mnt/sysimage" ... then you need to change it to root by giving "#chroot /mnt/sysimage"
@NehraClasses3 жыл бұрын
I think you did watch it properly, I did it from the rescue kernel image, not from single user mode.

@NehraClasses3 жыл бұрын
Rescue mode and rescue kernel both are different dear. The rescue mode is also referred to as the single-user mode. As the name suggests, the rescue mode is used when you want to salvage your system from a system failure, for example, boot failure or reset a password. In rescue mode, all the local filesystems are mounted. However, only salient services are started. Normal services such as network services will not be started. The rescue kernel is taking up space in /boot. A rescue kernel entry is created for every Kernel installation. A rescue kernel is marked as default after a Kernel installation.

In this method you don't need to manually remount the system as rw and no need to do chrooting. This rescue kernel just work like the normal one, but it is used for troubleshooting purpose.
