Comment(by vegardw):
I'm pretty new to DHCP myself, only started looking at it a couple of days
ago. But it shouldn't have any side effects.
According to the RFC the server must supply any parameters in the list it
can provide, and omit any parameters it cannot provide. So a server that
isn't configured with a domain name should simply return the other options
in the list, and omit domain name. So it shouldn't have any negative side
effects. The dhcp-client in linux requests several options that the dhcp
server doesn't supply, and the only thing that happens is that those
aren't sent from the server.
So it's more a case of the variable name being a bit misleading in my
opinion.
The domain name is the local domain / the first search domain that the
resolver tries when looking up a name. On my local network at home I use
the domain intra.vegardw.com, and for example my linux box is called
debian1.intra.vegardw.com. With the domain field set to intra.vegardw.com
I can just do 'ping debian1' to ping the server instead of 'ping
debian1.intra.vegardw.com'. So mostly it is for being able to address the
hosts in the local domain by using just the hostname instead of the fqdn.
