From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

[Solved] UUID for root reverted to previous UUID (lemmy.ml)

I suddenly got the same problem in /efi/loader/entries all conf files reverted to previous uuid (first post ). To change uuid I just edited all conf files with the correct uuid for root.

I don't know if manually changing was correct or if I should use some sort command.

Bootctl status

UUID in status is wrong.

I have no idea what is reverting UUID back to the wrong one after updating system.

I could just reinstall but if possible I would like to try to fix this and learn.

Edit: Problem was that in /etc/kernel/cmdline had wrong UUID. Changed it to correct one and dracut-rebuild uses correct UUID.

Ah, that would break things! Any idea how the incorrect UUID got into the kernel boot parameters?

It probably happened when I was messing with SSDs. I wanted a smaller one to be root and a bigger one as home.

Edit: Kind of happy that i managed to break something and fix it.

That is how you learn! Actually one of the best ways to learn, IMHO.
