The problem:
/sbin/dhclient-script does not update /etc/resolv.conf unless it
receives a domain name from the DHCP server. My DSL router doesn't
send a domain name. Hence, no /etc/resolv.conf file is created,
and DNS doesn't work.
I'm running 5.0 RC1, but the same problem exists in 4.6.2-RELEASE.
My recollection is that 4.5-RELEASE worked fine without getting a domain
name from the DHCP server.
I've attached a trivial fix for the problem to this email.
Basically, it creates /etc/resolv.conf as long as name servers are
sent by the DHCP server.
