The name of the configuration file should really be something that is
attached to the Server.  That being said there's no nice place to put
that right now...

That would work, but I don't like the way tomcat is currently handled.
It was done that way due to the necessity for a quick fix.  And has gone
beyond it's usefulness.  Not to mention the example you cited would be
for mod_jk versions...

Better to create a template based approach.  Attach a template to each
server (as in Apache Server or Tomcat Server) allowing customization of
the configuration files...  That way we don't have to adopt the tool to
each new version that requires a new configuration set.

There is an existing Jira issue
http://issues.apache.org/jira/browse/LOKAHI-4 where Ludovic was kind
enough to supply a factory approach to configuration building, which I
haven't had the time to fully browse yet.

There's no reason why we couldn't use that factory approach and have one
of the implementations be a class that generates a configuration file
based upon a velocity template for instance.  Or some other templating
engine.
