Puppet users - May 2009 - Using storeconfig data in a manifest

OK, this is how I think I''d like to solve my sample issue in the other
thread, but I don''t know if its possible now, or a future feature
request (if it makes sense.)

Sample issue: configuring haproxy on some servers, when the servers to
be included in the configuration will change.
The servers of all kinds are first booted, and know their role (web
server, proxy, etc) from the boot server.

The report this to puppetmaster.

Puppetmaster knows the the IP address of the web servers; it knows
the  template of the haproxy config.

Currently, I don''t see a way to use this information together in
puppet.

What would seem to make sense would be if you could query storeconfig
data in a manifest.

e.g. in psudeo sql:
 $webservers= &''select machine.ipaddress from storeconfig where
machine.role_webserver=true''

which would return an array of ipaddresses to the variable
$webservers, that could then be used in templates.
Is something like this possible now? Or make sense?

the direct solution would be to query the boot server from the
puppetmaster about this information, or the place from where the
bootserver knows.

Using an external node script should give you all the possibilities you
need.
