Would it be a good practice to install minimal Debian and learn to use Nix package manager with it?
Literally just what you said, it's that easy. The only question is whether you want to use any debian DE at all or not.
Debian has extraordinarily sane and basic defaults, whether you need it as a base for vms, lxc containers, nix and other overlays, or whatever.
If you want a system specifically to use the Nix package manager, just use NixOS.
Don't use Timeshift with BTRFS unless you know BTRFS. Timeshift will just fill the drive and make it unusable. It's poorly designed for BTRFS.
It's not necessary accurate to say timeshift is filing the drive. All timeshift is doing is the taking and management of snapshots. You could only have timeshift configured to keep 4 hourly snapshots, which wouldn't reasonably fill a drive. Now if you 6 monthlys configured, sure you could fill up drive no problem since it will take at least 6 months before deleted data is removed.
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?
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.
