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.

    I did my first BTRFS setup over the weekend. I followed the Arch wiki to set up what I thought was RAID 1 only to find out nearly a TB of copying later that it was splitting the data between the drives, not mirroring them (only the metadata was in R1.) One command later and I’d converted the filesystem to true RAID 1. I feel like any other system would require a total redo of the entire FS, but BTRFS did it flawlessly.

    I’m still confused, however, as it seems RAID 1 only works with two drives from what I’ve read. Is that true? Why?
