[Dnssec-trigger] OS X, resolv.conf

    	Right. It was just slightly confusing that it would actively pick up
    	what's essentially a localized setting from whatever DHCP was serving
    	me at the time, and stick it into the config file at install time. Maybe
    	it's just me :)

Probably not just confusing to you. One thing one can consider is
not install a search path at all (or always the nathing.valid
thingy).

PS. BTW, the behavior is documented:

       domain: "example.com"
              The  domain  to set in resolv.conf.  See resolv.conf(5).  Picked
              up once during installation, and not from DHCP since  it allows
              directing traffic elsewhere.

although it doesn't says from what it is picked up.
