Is there no way to pull this information from the resolv.conf file in an universal
way?  It really would suck having yet another location for DNS search paths
to maintain an environment.

And out of interest what would your intent be for those names who still fail this
qualification test?

e.g.

## Where minecraft "host" is really a fast alias to set username, an other
## information to correctly log into generic.server.com without having to
## hand specific them all the time.
Host minecraft   
	User minecraft
	Hostname generic.server.com
