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.

I haven't used them professionally but I've been using ZFS on my home router (OPNsense) and NAS (TrueNAS with RAID-Z2) for many years without problem. I've used Btrfs on laptops and desktops with OpenSUSE Tumbleweed for the past year and a bit, also without problem. Btrfs snapshots have saved me a couple of times when I messed something up. Both seem like solid filesystems for everyday use.

Why ZFS on a router?

[–] [email protected] 2 points 9 months ago (1 children)

The two options are UFS and ZFS, and their documentation recommends that ZFS is more reliable. I had UFS before and after a power outage the router wouldn't reboot, so I switched to ZFS. That was two or three years ago and the router has stayed up since then (except one time when an SSD died, but that was a hardware failure).

Honestly I'm surprised UFS is still a thing. I guess its useful for read only flash.
