if_ep has been a sore spot for a long long time, this is nothing new with
2.1.5, though it was broken in the initial release of 2.1.5 and then quickly
fixed.

I'll defer on that one... it is very site specifc as to how to proceded
with building things peice meal wise as to not disturb the running system.

Read and fully understand the /usr/src/Makefile world: target, most of it
can be done while up multiuser, but anything that is going to touch
binaries (and that includes /usr/lib) is best done without a load on the
system.

Those who claim that they have not had problems running ``make world''
on live systems are either very lucky (ie, there load we very light)
or they ignored the few programs that dumped core while versions of
things where out of sync.
