On NixOS:

    % find /bin /usr
    /bin
    /bin/sh
    /usr
    /usr/bin
    /usr/bin/env
/usr and /bin are only there to provide sh and env for compatibility with shell scripts.

If nothing is in /bin or /usr/bin, where do proggies live? And what does your path look like?

In the Nix store (/nix):

    % which cp
    /run/current-system/sw/bin/cp
Each package has its own path in the nix store:

    % readlink $(which cp)
    /nix/store/l96gc2qb8ysnf5hcq1hp5a3r6x905rf4-coreutils-8.31/bin/cp
The current system and previous systems also live in the store (Nix has atomic upgrades/rollbacks). Each system can be seen as a package with symlinks to binaries, man pages, etc. in the store. More information about the motivation behind Nix's approach can be found in Nix Pill 1:

In NixOS, they are probably under some directory with a random name.

This is the OS where each binary runs with a different path and library path, with only the programs it needs (on the versions it needs) linked there.
