What is the difference between the two?
I had thought that domain-name would put the client on the specified domain (ie. If the domain-name was set to "foo.bar" the clients FQDN would be 'hostname.foo.bar'), but http://linux.die.net/man/5/dhcp-options seems to imply that both options ('Domain-Name' and 'Domain-Search') simply specify a search domain.
If domain-name does not set the domain for the client, what option would?
