This sounds like a good workaround for the bug in 'network-manager'.
I'll test it and
send you a message to see if this fixes the problem.

On the same principle it might be better to move the /etc/init.d/umountnfs(.sh)
script to /etc/network/if-down.d/ and take those parts unrelated to
the network file
systems and create new script like 'umountvfs' for virtual filesystems
(or integrate
it in another existing one if possible).

Thanks

PS: this problem in NM applies to Lenny too.
