STALE MOUNT HANGS LS

Often times a stale NFS mount
point can hang a long listing
of a directory (ls -al).

To avoid this make the mount
point down one level.

So instead of:

mount rocket:/people /people

If the system rocket was down
the chances of a long listing

% ls -al /

of the root directory would
hang for a long period until
the NFS mount timed out.

Avoid this with most flavors
by

mount rocket:/people /rocket/people

then a long listing of root

% ls -al /

would work, but

% ls -al /rocket

would hang due to the stale
mount point.
