Before, we required that the mount target exist and be a
directory for the 9p mount to successfully complete, which is not
how things are supposed to work - the user should be able to
mount anywhere. This should just be a simple mkdir, but with FCOS
the root directory is immutable so we need to undo that before we
can mkdir, and unfortunately we don't have a library that can do
chattr (and I didn't want to drag in a new dependency just for
that), so let's be gross and add it to the SSH command. I
aggressively dislike this but it does work.
[NO NEW TESTS NEEDED] Can worry about getting a more generic
mount test together for Machine later.
