dhclient (part of the net-misc/dhcp package) does not setup NTP servers in the variables it exports. I really think it should as the DHCP protocol does allow for this - and I need it for working @ home and work ;)
Created attachment 39489 [details, diff] enables new_ntp_servers This very small patch enables NTP servers to be exported correctly so that the dhclient-script can set them up
Fixed in dhcp-3.0.3
