Never liked it on pc, but I have it on phone and love the ability to have 2 dirs open at the same time.

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.

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

Will have a look.

I used arch-chroot. I mounted efi to efi dir with mount and used mount -o subvol=@subvolname to sub vol dir. Just incase i will reinstall nvidia drivers when booted normally. I will read about initrd. Thanks for all the info.

I have systemd-boot.

[You are right. In systemd-boot entrie it is used for root uuid. I should replace it with my root uuid right?]

Edited entrie to my root uuid and it boots. Thanks for helping me.

Zygisk is part of magisk. Might be wrong but its just root method used by magisk.

It doesn’t really matter if it’s usefull for others. Write it for yourself and learn from it. I myself wrote copying script for terminal and I am sure no one else going to use it just me and thats fine.
