So it looks like the current hostname only comes into play at the
hostname.pl config file load level? Or does the load of config.pl also
have $_[1] set to the hostname.

I already use the link idea where I can, but that is still a
maintainance nightmare. What I would like is rather than a link, a
file to be loaded with the group level info (specified in the hosts
file somehow) that I can manipulate.
The hostname location in $_[1] may do the trick however. Thanks for
that bit of info.
