Oh bugger.  Yes, of course root_squash is on.  Quite deliberately for
general security reasons; in fact, the system is so secure, it's not
working ;-)

Chocolate fish for you Todd; thanks for pointing out what should have
been fairly obvious.  I'll drop the root_squash for long enough to catch

other directory.

Thanks again,
