Thanks for the suggestion, but I don't think that's our culprit.  For
a start, very few people have login access to the NFS server.  Also,
the start of and lulls in rebooting seem to be roughly correlated with
minivend activity.  Minivend does two things which might be related to
the panic: named pipes (over an NFS-mounted file, with the client and
server on the same machine) and file locking using flock.  This could
just be a red herring, though.

The other mention I found of this in the bugs database related to a
version of bash which we don't have installed.

Just in case, I'm chmodding 700 mount_msdos on all our systems. :-)
