Me too! I updated to 6.0-RC1 last night and I had the same problem. The 
dhclient.conf(5) man page appears to document the old ISC DHCP Client 
rather than the new OpenBSD implementation.

My /etc/dhclient.conf file (which worked with the ISC version) looks 
like this:

interface "xl0" {
         supersede domain-name-servers 10.0.0.1;
         supersede domain-name "mydomain.com";
}


I am also getting these same messages:

Oct 21 15:10:28 workdesk dhclient[5516]: Bogus domain search list 15:
domain_not_set.invalid (domain_not_set.invalid)
Oct 21 15:10:28 workdesk dhclient[5516]: Invalid lease option - ignoring
offer

My question is: How can we get dhclient to ignore/override the domain 
search list field so that it accepts the lease?
