When pump talks to a DHCP server, it overwrites /etc/resolv.conf with the site-specific resolver information. In many instances, I would like to use a constant domain search path, regardless of where I am. Might it be possible for pump to emit a fixed "search" line in /etc/resolv.conf whenever it rewrites this file?
Already happens. Check man pump and specifically the section on pump.conf. Basically, just create an /etc/pump.conf with contents of domainsearch "mydomain.org redhat.com" and it will always set the search path to what's specified
