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.

This is how we used to do it before we had NixOS with impermanence mode. https://nixos.wiki/wiki/Impermanence
Probably a cleaner way indeed but again mindful about how familiar people who can help the library are with NixOS vs Ubuntu/Debian.
All it takes is one person to share a complete config and I’d assert that it’s actually easier than Ubuntu/Debian to setup (especially if you’re talking about deploying a fleet of identical configurations or even a config that lives on a liveISO meant for installing the OS with these options baked-in).
Granted it’s not there yet and you’re correct but soon: One-click deployment would make it even easier than Debian/Ubuntu.
Also, IMO Nix is a force-multiplier. For example, I alone could probably configure a whole fleet of systems declaratively with Nix AT LEAST as well as a config script repo that has 20 people contributing to it since, in Nix, if it builds, it’s pretty much ready for production.
The fact alone that Nix allows you to simply list the software you want on the computer and it takes care of everything else (rather than a long, error prone sudo apt-get install command list that may or may not install because dependencies aren’t locked) would cause me to select Nix every single time.
I’m just kind of bewildered how anyone can argue against Nix by invoking a method of Linux install where you sudo apt get 400 commands in a precise order (and if you accidentally go out of order, you might screw up your system) and you also have to carefully manage dependencies and will be SOL if one piece of software requires one version of python while another requires an entirely different version.
Maybe I'm misrepresenting the labor market and the availability of professionals working with Nix. That's also why I mentioned Ubuntu/Debian not on the basis of technical merit but "just" popularity. Now if you are suggesting that they could hire somebody working with Nix just as easily for that task, sure they could go for it.
