We had this already. There's no such thing as a "correct" order of error
messages. EROFS is as correct as EEXIST. If coreutils don't allow
different correct error messages to be returned, than coreutils is just
not foolproof enough. If this isn't a problem with coreutils, than the
better.

See my previous mail on this subject.

See above.
