The "ByteString" in the SYstem.Posix.*.ByteString modules applies to the
pathnames (POSIX pathnames are byte strings, and there's lots of ways to
cause problems if you insist on pretending that they are in any particular
encoding), not the values being read/written, so functions like that are
basically carried along just to provide a mostly compatible API.

I would expect to find functions working with ByteString values under
Data.ByteString.
