That all fine (see my previous post)

It's an NFS mount: 

raimund at fides:~> df -T /work/nld
Filesystem    Type   1K-blocks      Used Available Use% Mounted on
nfs.bb.xyz.org:/work
               nfs   104964896  80818144  24146752  77% /work

No, tcsh exhibits the same behaviour.

Yes, that's the only difference I can see.

raimund at fides:~> ps -eo "%p %y %x %c %g" |grep $$
 7919 pts/1    00:00:00 bash            users

Are there any global shell settings somewhere in the system that may be broken 
in 10.1? BTW: I can't change into the /work/nld directory with Konqueror as 
well (probably because Konqueror is running with my default group membership: 
users). Again, on 10.2 Beta2 it works just fine.

Cheers,
Taimund

Buy a Pentium 586/90 so you can reboot faster.
