Well, OpenPKG by default doesn't use directly this approach with the
stand-alone config packages you describe. But if you look at LAMP-based
packages like "cacti", "wordpress", "drupal", etc. you will see that
they all depend on the same "apache" package but all run their own
dedicated Apache with an own configuration. So, with OpenPKG you can
achieve what you wish. If you in additional then set "apache_enable=no"
in <prefix>/etc/rc.conf the original "apache" package not even starts up
by itself. Then only the Apaches in your config packages would fire up.
The same approach you can do with other packages, too.
