[Tfug] Partition read/write

[erich]

OK,
    I just rebuilt a package suspected of causing the problem, and
it pulled thru without a hitch. That's right. Under normal circumstances
one cannot umount the /usr partition. A busy error is returned.

                                                  Erich
