Comment 15 for bug 1759014

Can we add support in the patch for setting 'UseDomains=false' or 'UseDomains=route'? This would allow ignoring the search domain provided by the dhcp server, which is useful when running in clouds that don't allow overriding this field. This use to be possible by setting the 'supersede domain-search' option in /etc/dhcp/dhclient.conf
