In Nixpkgs, there are generally three different names associated with a package:
- The `name` attribute of the derivation (excluding the version part). This is what most users see, in particular when using `nix-env`.
- The `pname` attribute of the derivation. This is what most users see, in particular when using `nix-env`.
- The variable name used for the instantiated package in `all-packages.nix`, and when passing it as a dependency to other functions. Typically this is called the _package attribute name_. This is what Nix expression authors see. It can also be used when installing using `nix-env -iA`.
- The filename for (the directory containing) the Nix expression.
Most of the time, these are the same. For instance, the package `e2fsprogs` has a `name` attribute `"e2fsprogs-version"`, is bound to the variable name `e2fsprogs` in `all-packages.nix`, and the Nix expression is in `pkgs/os-specific/linux/e2fsprogs/default.nix`.
