Hey,

I am planning to implement authenticated boot inspired from Pid Eins’ blog. I’ll be using pam mount for /home/user. I need to check integrity of all partitions.

I have been using luks+ext4 till now. I am hesistant hesitant to switch to zfs/btrfs, afraid I might fuck up. A while back I accidently purged ‘/’ trying out timeshift which was my fault.

Should I use zfs/btrfs for /home/user? As for root, I’m considering luks+(zfs/btrfs) to be restorable to blank state.

    Many many years ago I set up btrfs for the disks I write my backups to with a raid 1 config for them. Unfortunately one of those disks went bad and ended up corrupting the whole array. Makes me wonder if I set it up correctly or not.

    Nowadays, I have the following disks in my system set up as btrfs:

    • My backups disk because of compression.
    • My OS drive because of Timeshift.
    • My home folder because it feels safer. COW feels like it’ll handle power failures better, whilst there’s also checksumming so I can identify corrupted files.
    • My SSD Steam library over two drives because life is short and I cba managing the two ssds independently.

    It’s going fine, but it feels like I need to manually run a balance every one in a while when the disk fills up.

    I also like btrfs-assistant for managing the devices.

    Out of interest, since I’ve not used the “recommended partion setup” for any install for a while now, is ext4 still the default on most distros?

      You do know that Steam handles multiple libraries transparently, even on removable drives?

        I know they all show up in the same interface and I can move games between drives in the storage interface.

        But I don’t want to deal with having to shuffle things around to install a 40GiB game where both drives only have 30GiB free. Or having to remember which of the two drives has a specific game on when I want to find their files.

        It also gives a possibly-insignificant speed boost and extra cool points.

      I recently installed Nobara Linux on an additional drive, because after 20 years, I wanted to give Linux gaming another shot (works a lot better than I had hopes for, btw), and it defaulted to btrfs. I’ll assume so does Fedora, because I cannot imagine Nobara changed that part over the Fedora base for gaming purposes.

        Fedora does, with compression enabled. It’s one of the largest divergences from Red Hat since Red Hat doesn’t support it at all. openSUSE does also.

        This was ages ago, so I can’t really remember I’m afraid. I think maybe the files themselves were corrupted, not the folder structure, so perhaps? Although I can see that as a thing I forget to do though.
