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.
The two options are UFS and ZFS, and their documentation recommends that ZFS is more reliable. I had UFS before and after a power outage the router wouldn't reboot, so I switched to ZFS. That was two or three years ago and the router has stayed up since then (except one time when an SSD died, but that was a hardware failure).
