I am wondering, would it be possible to (automatically) create pkg-plist info 
for the NO_* targets in make.conf? We could put that into the ports-tree 
somewhere and if you'd like to remove something completely you can install 
the dummy port & pkg-plist and use pkg_delete to clean up.

It seems to me that it might be possible to add some kind of Makefile hint 
variables (i.e. define a variable in Makefiles/targets that depend on NO_*) 
that'd help to generate filelists for the NO_* targets. If this is the case 
it should be possible to place pkg descriptions into /var/db/pkg during the 
installworld pass. This would also make it easy to get rid of things after a 
CDROM install.

What do you think?
