Ok, I spent most of today adding ByteString alternatives for all of the functions in System.Posix that use FilePath or environment strings. The Haddocks for my augmented unix package are here:

In particular, the module System.Posix.ByteString is the whole System.Posix API but with ByteString FilePaths and environment strings:

This looks lovely -- thank you. Once it's released, I'll port all my libraries over to using it.
It has one addition relative to System.Posix:
getArgs :: IO [ByteString]
Thank you very much! Several tools I use daily accept binary data as command-line options, and this will make it much easier to port them to Haskell in the future.
Let me know what you think. I suspect the main controversial aspect is that I included
type FilePath = ByteString
which is a bit cute but might be confusing.
Indeed, I was very confused when I saw that in the docs. If it's not too much trouble, could those functions accept/return ByteString directly?
