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.

it's the way Nix works too
Could you elaborate? I was under the impression that NixPkgs stored the hash of their dependencies and when launched create an environment to use them, this way two apps can share the same library when the version is the same.
Nix doesn't do anything special when launched.
The way it works is very simple - instead of e.g. /usr/lib/libssl.so.3, binaries use /nix/store/openssl-.../lib/libssl.so.3. This is done at build time, not runtime.
