do it's job it would have to choose between two cases:
1. either it would take a very long time to get the correct adjustment, thus,
if you are not currently on the net right, you wait a long time (or must
type ^C, which is ridiculous)
2. ntpd could be modified to "abort early", but then would not meet the
promise made by -s in the manual page (note: it does not say that it
"tries")
therefore, -s and -S must become user choices.  Sorry.  This same choice is
made in lots of other places

relevant when the dummy ruleset can't be loaded, we still want to enable
pf, otherwise the real ruleset (even if that does load correctly) won't
be active. might happen on a non-GENERIC kernel or after an update (before
/etc is manually updated). reported by Jim Rees. ok frantzen@
