Multi-user Nix systems use a "nix daemon", which user's commands send requests to ("please build this version of Firefox with this version of GCC, etc."); all of the results go in the main "nix store" (usually /nix/store). Nix doesn't store duplicates; a hash is calculated, based on the inputs (source code, compilers, libraries, etc.) and if an output with that hash already exists, it will be used. If not, the configured binary caches will be queried, to see if a pre-built binary can be downloaded. If not, the inputs are fetched (following the same process) and the build is performed. |
