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.
After 4 years on btrfs I haven't had a single issue, I never think about it really. Granted, I have a very basic setup. Snapper snapshots have saved me a couple of times, that aspect of it is really useful.
