However, this is still somewhat of a brute force method for piecing things together - I thought there was some kind of elegant mechanism where you could edit make.conf or something, so that when you did a make world, it would skip the components that you didn't want to - and you could control it with much more granularity than you can in the custom menu in sysinstall ... does this sound familiar at all ?

You have to edit /etc/make.conf and add NO_xxx lines in it (look in
In addition, I use custom CFLAGS when possible. Sometimes -Os produces
broken code (X11 comes to mind).
My /etc/make.conf looks like this:
CFLAGS=-Os -march=c3 -fno-strict-aliasing -pipe
[more NO_xxx lines]
I then install the new world in a separate directory:
make world DESTDIR=/itx
But even though this procedure gives a minimal system, it is too big
for my requirements (FreeBSD + X11 + rdesktop in 16MB). I am still forced
to pick and choose components by hand.
