Due to the fact that scripts which are ordered before
early_late_divider in the second run are not executed (see rc), if a
script gets reordered into the early phase as a result of including
the local startups, it won't be run at all. On at least one of my
systems that's happening to resolv (in both HEAD and RELENG_6). It
goes from close to last in rcorder (after securelevel) to absolutely
first after you include the local startups I have (nothing exciting,
just a few ports).
Currently resolv is a little thin in terms of ordering hints. It
contains only PROVIDE and KEYWORD, and nothing REQUIREs it. Can
someone who knows what this script is for (brooks?) add either a
REQUIRE in or for resolv, or both? The CVS logs seem to indicate that
it's related to diskless booting, so I don't want to touch it if I
don't have to. :)
FWIW, I use the attached patch to rc to debug this problem.
