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.

Yes, and every package specifically defines the exact version of its libraries that it needs and the system symlinks everything together package by package, so there's no chance than an update will break something further upstream. The configuration file also controls things like MySQL configuration and user permissions so you can get literally the exact same system. I think even docker doesn't control for library versions with its regular configuration.
EDIT: And it keeps older versions of the configuration file and its symlink arrangement around, so if something goes wrong, you can reboot the machine and select an older version from the bootloader.
Definitely docker (well, let's say containers) control the library version, if you didn't build the image specifically not to do that (e.g. fetching dependencies at runtime, which is generally a bad practice and not the default).
However, at build time if you use things like "apt install ..." You will get different versions depending on when you build the image, but once the image is built, you have always the same software inside. Obviously it is very different from nix as they serve very different purposes (one day I will find the motivation to switch to nixOS!).
Wow, that's great! I'm not sure if I need those features, but I'll check NixOS out, thanks
