  i think that would be useful as i'm in the situation of wanting to
have a massive archive of S/W tarballs available for students in
various embedded linux classes that they can take advantage of for
their builds, but i (unsurprisingly) want that to be a read-only
directory so they can't make a mess of it or arbitrarily add anything
to it.
