    Ok, I don’t get it. Can you explain it to me?

    [–] 0x4E4F@infosec.pub 53 points 10 months ago (3 children)

    Timeshift works only with BTRFS subvolumes, thus, if you wanna have backups (snapshots), you have to have subvolumes and not install in the root of a BTRFS filesystem 😔.

    That's only to backup/rollback the root though, right? If one's looking to backup - say - their home dir, they can just recreate the home as a subvolume without reinstalling the system. Or am I mistaken?

    You can definitely do this with a few commands.

    https://github.com/raldone01/config_fish/blob/main/tdcff_functions/btrfs_folder_to_subvol.fish

    Because I often forget to do it I wrote a little helper script.

    This file can be run or sourced and only depends on btrfs-progs and fish.

    Awww man, thanks ☺️.

    Good thing I love fiish, it's my default shell 😉.

    Yes, you can just set it to mount a, let's say @home, subvolume to /home and that's that, done.

    [–] Turun@feddit.de 7 points 10 months ago (1 children)

    If you want to you can just create a new subvolume, mount it temporarily and move all your files from root to there. Then you need to figure out how to make the new subvolume your root directory upon boot and you are done.

    [–] 0x4E4F@infosec.pub 1 points 10 months ago* (last edited 10 months ago)

    I know how to do that, you set the subvolume as the default one, thus, when mounting, if no options are passed, it always mounts that subvolume as root.

    But, you have to disable that. Sure, I set it during install, cuz installers are stupid (if you tell it to install in /@, it will most probably moan), but disable it after first run (set the real root as the default subvol, i.e. mount point) and just add subvol mount options in fstab.

    It's just extra steps I have to do now 😒, that's why the rant.
