Not as obvious, but this bug leads to huge closure sizes (such as including all of GHC and its docs). Especially painful when using nix to build docker images.

@m4dc4p You mean this affects packages which have only executables and internal libraries?
Note that you can currently work around this by applying the function haskell.lib.justStaticExecutables to the resulting packages.

I'm still inclined to think that this is a Cabal bug as well, Setup.hs copy should not install things that are not supposed to be installed.

@maralorn That doesn't work when the executable also includes an internal library. (We were already using the justStaticExecutables function). Moving the executables to their own package does work, however, if the shared library uses the Cabal data-files feature, you still end up with a closure that depends on GHC. See NixOS/nixpkgs#155924 (comment).
