That works indeed fine, if you have _ONLY_ Linux NFS servers in
your net. Unfortunately we have some servers still running Solaris
or IRIX. These machines also have more than one single /-filesystem.
With the approach above you can't access the additional filesystems
on the Solaris/IRIX boxes. So I have to wait what will happen first:
1. I can convince our people to replace IRIX 6.5/Solaris with MIPS/Sparc Linux
on our Origin 2000 Server and Sparc systems. (Relatively unlikely :-( )
2. Those Servers aren't used any more, since our new Dual P-II PCs run
every of our applications at least twice as fast under Linux.
(More likely)
3. HPA finishes autofs v4.x which may (will?) support this difficult stuff.
(Don't know how likely this is ... hint hint hint ;-)

Indeed this works fine. As long as you don't need to access data
on a None-Linux NFS server... :-(
