Local devices vs. Gutsy

[Richard Doyle]

We upgraded our lab from Feisty to Gutsy over the last couple of weeks.
All was working well until I noticed that no more than one client could
use local usb drives, as described in bug 160240
(https://bugs.launchpad.net/ubuntu/+source/ltsp/+bug/160420) .

The discussion of the bug in that thread provides two solutions: either
(1) hack $client/usr/share/ldm/rc.d/S20-delayed-mounter
and /usr/sbin/ltspfsmounter, or (2) don't log into the server with 'ssh
-X <user>'.

I implemented the first solution, but we now have a number of problems,
such as intermittent PXE boot failures, freezing clients, and other
instability.

Can multiple thin-client users actually use local devices under solution
(2)? I'd have to give up remote access via NX, but the clients would be
able to access local devices. 

What do the developers recommend?
