From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

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.

@unhinge I run a simple 48TiB zpool, and I found it easier to set up than many suggest and trivial to work with. I don't do anything funky with it though, outside of some playing with snapshots and send/receive when I first built it.

I think I recall reading about some nuance around using LUKS vs ZFS's own encryption back then. Might be worth having a read around comparing them for your use case.

afaik openzfs provides authenticated encryption while luks integrity is marked experimental (as of now in man page).

openzfs also doesn't reencrypt dedup blocks if dedup is enabled Tom Caputi's talk, but dedup can just be disabled
