Sometimes a puppet class (or .erb file) wants to resolve a hostname. That works fine in production, and works fine on a VPS-local puppetmaster. But when we try to compile a manifest on labs-puppetmaster it can't resolve anything under .wmflabs
It would probably be simple to have the labs puppetmasters know to look at labs-ns* to resolve things under .wmflabs. Is there any reason not to do that?
