help with condensing bsd

[krad]

Thats what boot environments are for. Create a blank filesystem and then do
and install with the dest-dir installed. make delete-old etc should take
care of a lot of the issues. You could of course use pkgbase to create your
base image, and you can strip bits off afterward quite easily. However as
you a re doing a custom build there is no getting away from /usr/src, until
pkgbase becomes standard in maybe 12, or 13.
