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.
Yes it is great. For me snapper rollback was an awesome onboarding experience to linux. Being eager to try things I read online for tweaks and general explorarion it brought me back to a working system after some custom kernel compiling gone awry, or deleting the wrong file etc.
I've been on btrfs for so many years, with nightly backups with restic, so I've been dragging my feet on snapper. Finally installed it a couple weeks ago, and while I opened the config, I don't think I changed anything. It's worked so well, and the Arch package was so well done, that I'd forgotten I had it installed until a few days later I noticed that it was taking snapshots every time before I installed something. It's shockingly good, and I don't understand why btrfs+snapper(+grub-btrfs) isn't the default on installs now.
