Assuming all the dns servers are getting the same config, We break big chunks
like that out into their own modules. So:
node dns1.myco.com {
include myco::dns
}
node web1.myco.com {
include myco::web
}
If the servers have different configs, you can make myco::dns::common,
myco::dns::this myco::dns::that myco::dns::other.
We also use a "role" fact instead of a regex on the fqdn for case statements,
but even those are fragile. I prefer to explicitly include things in the node
definitions. It's a bit verbose, but its also clear for anyone else that has to
maintain the code.
