And the answer is "it doesn't".
At least not on Solaris 9 or Linux.
I don't know about OpenSolaris or Solaris 10.

The reason I was confused is because of the internal contradictions in
you original two postings.

But, if you could have described the semantic rules which allowed that
apparent contradiction work the way you described then I would have been
happy to listen.

Yes, with autofs version 4 use "/net /etc/auto.net" in the master map
which generally should work the way you expect. The internal hosts map
is available in autofs version 5, which I suspect may be called autofs5
in ubuntu.

I don't know how zfs may change any of this either.

A wildcard map for an indirect map, which home directories usually are,
might be:

*	<home directory server>:/<home directory base directory>/&
