Maybe I'm missing something here, but I think Jon was asking something a bit different -- he doesn't want to check the validity of the erb template (i.e. ruby syntax check) but syntax check the named zone file generated by the template. So the tricky bit is how to get the variables out of the puppet manifests that the erb template needs to generate the output file that 'would' be generated by a new puppet run for this node -- without the actual puppet run (as he asks at the end of the email). My first thought is that the only accurate way to do this is by doing a full puppet run, as any part of the node's manifest could effect the variables used in the zone file template. You should be able to get away with a --noop run so the changes won't actually be applied (because noop does generate files from templates, but you would need to have a way to capture the newly generated zone file on the client host and run the named-checkzone there.
