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.

    Can’t vouch for ZFS, but btrfs is great!

    You can mount root, log, and home on different subvolumes, they’d practically be on different partitions while still sharing the size limit.

    I would also take system snapshots while the system is still running with one command. No need to exclude the home or log directories, nor the pseudo fs (e.g. proc, sys, tmp, dev).
