Yup, that's exactly how you do it.  I have to do this all the time,
unfortunately, with K12LTSP installs.  The reason is that I typically
use a 10/100 NIC for the outside interface and the Gig-E one for inside,
and Fedora gets it backwards from what I need the order to be.  Now,
that's something that GNU/Linux distributions ought to let you choose at
install time.
