Just for confirmation, I did exactly that with only the teTeX
directory mapped to /Volumes/Beta/usr/local/teTeX in order to not
interfere with any applications relying on hard-coded paths, and it
By the way, I tried something similar with mapping /var/tmp to
another partition when I was running out of space on my OS partition,
which caused all application installers built using Installer Vise to
crash, although the command-line path using the symlink (/var/tmp)
was the same as before; some apps seem to be unable to resolve symlinks.

Sounds great, too, but as long as the simple symlink works, I'll
stick with that... :-) (especially since the OSX way of automounting
seems to be based on a different concept than other Unixes, at least
I did not find out yet how it really works)
