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.

Several years ago now. On at least two of those tries, after maybe a month or some of daily driving, suddenly the fs goes totally unresponsive and because it’s the entire system, could only reboot. FS is corrupted and won’t recover. There is no fsck. There is no recovery. Total data loss.

Could you narrow it down to just how long ago? BTRFS took a very long time to stabilise, so that could possibly make a difference here. Also, do you remember if you were using any special features, especially RAID, and if RAID, which level?

I could see if there's notes somewhere. Very plain desktop and laptop. Probably encrypted LVM. At least one was doing a lot of software builds with big system image trees and snapshots.
