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.

    Most of the tools now should be setting nocow for virtual drives, performance these days isn’t bad.

      nodatacow is a hack and will disable any and all consistency mechanisms for that file’s contents. Tools should not be setting nodatacow for virtual drives, certainly not by default.

        Default libvirt behavior since 2020. Pretty sure some database tools turn it on too.
