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.

Hi everyone!

I saw that NixOS is getting popularity recently. I really have no idea why and how this OS works. Can you guys help me understanding all of this ?

Thanks !

I like using btrfs with Arch because of the snapshots. If an update breaks something I can just boot into a snapshot from grub keep using my PC and solve the problem later. It's very useful... yes... very... you should try it... come... try btrfs... it's warm and cozy... INSTALL IT!

I have tried btrfs in the past and when it goes wrong you are utterly shafted. You can't even mount it as a read only file system, it will just lock you out entirely. And the support isn't great, I ended up finding something that had a disclaimer along the lines of "only run this if you really know what you're doing", but obviously I didn't as the documentation didn't tell me enough to know. So the only people who could possibly know are the developers of the file system themselves. Anyway, I was 2 days in to trying to recover my data by this point so I gave it a go, nothing to lose - it refused to do anything. Great.

So in summary I'm not going to try it again.

can confirm, I've recently had my btrfs partition on NixOS go permanently read-only because it ran out of metadata space (which you can't extend without write access, even though btrfs does reserve 0.5GB of metadata space) so I've switched to bcachefs
