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.

Btrfs has come a long way in the last few years. I have been using it for a little over 5 years and its rock solid. It now powers all my bare metal machines and I use Raid 1 on my servers.

There was one time I had a disk unexpectedly go bad (it started returning bad data on read) which lead to the system going read only. It took me about 5min to swap disks and it was fine. Needless to say I was impressed that no data was lost.

Btrfs will normally won't get corrupted unless you have a hardware issue. It uses cow so writes can never be half competed. If you do manage to get corruption you can use btrfs check.

From my experience BTRFS is way more reliable against hardware failure then Ext4 ever was. Ext* filesystems tend to go corrupt on the first and smallest power loss or hardware failure.
