automounter peculiarity, and a nice automount example

[Brent Callaghan]

Watch out for relative references between filesystems.  There may be an
implicit assumption that all three filesystems within /usr/local are
concurrently mounted - this may not be true using a map like the above
example.

For example: a symbolic link "/usr/local/bin/foo" could be a reference to
"../lib/foo".  The symbolic link will fail if "/usr/local/lib" isnt
currently mounted.  The automounter will not do the mount because the
relative pathname doesn't go through the automounter's mount point
(/usr/local).

BTW: It's not a good idea to mount executables "soft".  If the server goes
down while the executable is running you can get a SEGV or similar crash
when a page-in fails.  I prefer "hard,intr".
