* Throw better error when conf files are missing Previously, if some directories were missing .conf files, an error like this would be thrown: cp: missing destination file operand after '/nix/store/pnmrz06g0sa4s3yx53hgmr9k8jrh6ww0-ouroboros-network-framework-lib-ouroboros-network-framework-0.1.0.0-haddock-config/lib/ghc-8.6.5/package.conf.d' While normally this shouldn't occur, I've seen it happen in CI anyways, with the problem disappearing if the store path that's missing the files was rebuilt a couple times. With this commit, it becomes much easier to figure out which store path is missing the files, which would be very hard to figure out from the previous message.
haskell.nix is infrastructure for building Haskell packages with Nix
haskell.nix can automatically translate your Cabal or Stack project and
