Hm, ok, will have to check that out.

Maybe prepend is the wrong keyword, or try
prepend domain-name "mydomain.com "
Note extra space ^
Hint: dhclient's magic is done via a script, /etc/dhclient-script. If you
don't want both in the search path then use the `supercede' keyword
instead of `prepend'.

No. dhclient configures all Ethernet interfaces by default, but you can
specify with interfaces to listen on via the command line, like
dhclient ep0
to specifically listen on ep0.

Perhaps you have both?
