HP-UX 10.00 and later ships with an automounter running with a -hosts
option, so it's easy to just say "/net/hostname/directory/...", and the
automounter will do the rest.

If you like, you can put symbolic links in to make things easier, for
example:

  /x1        -> /net/x1/x1
  /usr/valid -> /net/x1/valid

While this is convenient and easy to do, using explicit automount maps
(ex: /home/username) is usually a better idea in terms of keeping things
"tight" and maintaining server/disk independance.
