Yeah, I looked at the man page for 'exports' and 'exportfs' and
remained unenlightened.

Aha, hadn't heard of that one before.

# showmount
Hosts on euclid:
10.0.1.101
10.0.1.103
10.0.1.85
10.0.1.87
10.0.1.89
10.0.1.9
erdos.home
harry.home
merlin.home
pythagoras.home
socrates.home

(Odd... the only one of these that is currently mounting anything from
this server is erdos.  'showmount -a' lists erdos as having
/archive/mirrors mounted even though it isn't, and refuses to mount.
Perhaps I need a way of resetting the server's idea of what clients
are connected to it?)

# showmount -e
Export list for euclid:
[...snip irrelevant entries...]
/archive/mirrors/suse      *
/archive/mirrors/gentoo    *
/archive/mirrors/sysresc   *
/archive/mirrors/knoppix   *
/archive/mirrors/mandrake  *
/archive/mirrors           (everyone)

Precisely the same (I tried that earlier, forgot to mention it).

euclid:/archive/mirrors /archive/mirrors        nfs     ro      0	0
