Almost certainly. But we aren't running your filesystem tests yet because they are still under experimental. There are probably a lot of POSIX assumptions everywhere in there given the root_name parsing business.

That one's up to you. I don't think the specific message matters to this test; clearly the existing asserts for `io_errc::stream` don't care about a specific message (which is why they worked on our implementation).
