Hi Ken!
Thanks for the reply!
The first two could be solved as one using 'hostname --fqdn', meybe even
the third one.
I decided we should solve this the proper way and update dhcp to specify
option domain-name klientdrift.uib.no uib.no
But since our clients will wander around the globe we want to specify
the certname in the puppet.conf. Is there any other caveates when it
comes to naming we should know about?
