Isn't the -F switch meant to do exactly that?

I have been using a pkg_comp chroot for building packages in the past
(as described here:
<http://www.netbsdfr.org/wiki/doku.php?id=howto:pkg_comp>).

In the past, I used to update packages manually and only when I
absolutely had to by entering the chroot environment and running make
update where needed, until I got really too busy to keep doing that.
Recently (i.e. the day before yesterday) I decided to give pkg_rr a
try for the first time, and have been running it on and off in the
pkg_comp chroot since then.  It is nowhere close to finishing yet
(this is on a laptop that is travelling a lot).

Any suggestions for better solutions would be quite welcome of course.
