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.

Question about the video. I've never used btrfs or Timeshift, so maybe this is just a thing with them, when he jumps to the CLI and unmounts, remounts RW, changes the @rootfs @, adds a dir and then mounts the subvolume on /dev/sda2 to /target.
This is totally new to me and I was wondering if anyone had an explanation as to why this was necessary?
I'm used to EXT4 and that's what I run. But if BTRFS has FINALLY gotten stable and usable and I can take snapshots and roll back to older ones, kind of like branches in ostree, then maybe it's worth this little extra work.
From what I find subvols are their own isolated branch with their own hierarchy. Is this how they're meant to be used? Manually creating them and mounting/unmounting?
Also anyone know if JustALinuxGuy is on Fediverse/Mastodon or a way to reach them about uploading these incredibly instructive videos to Peertube such as TILVids?
