[Solved] UUID for root reverted to previous UUID

Endrom@lemmy.ml to Linux@lemmy.ml – 18 points –

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.

I used gparted, blkid, checked fstab and by-uuid dir and no partition or drive had that UUID.

Weird… the only thing I can think of is that maybe the UUID changes on every boot with live USBs, since the root filesystem is ephemeral …

I think I found what changes root UUID. When I used dracut-rebuild all entrie UUIDs changed to the wrong one. Now I have to find how to stop that.
