It's not a specific snapshot that doesn't work. It's all snapshots, regardless of how old or new, that don't work.
So as of right now, i cannot use the snapshot functionality and cannot rely on my system backups. So if i were to brick my installation right now, my system would be lost and i could not restore any snapshot.
I didn't try "booting" into a snapshot from commandline because i don't know how. You said i should RESTORE a snapshot from TTY and that is something i don't want to do right now as my installation is working right now and i don't want to brick it by restoring snapshots that don't work.
To summarize:
My installation works fine, i can boot it, i can use it, 100% works. But if i go into the Snapshot section in grub when booting, and trying to boot in ANY of the snapshots (even ones i made just seconds ago on my working system) i get the "bailing out bcs sbin/init missing" error.
I can then easily reboot into my system and use the current installation, but i don't have access to ANY of my snapshots, making the backup / snapshot system broken right now.
That stresses me out because i need to have a working snapshot system in the case i break my installation at some point...
