What I was trying to achieve, which I haven't done yet, was a smallish dump of the "core system". By that I mean system + ports, without distfiles, etc. Then a separate dump of user data, which is considerably larger. At this point I am thinking I should do this: make clean distclean ports to remove temporary stuff set /usr/home NODUMP dump /, /var, and /usr unset /usr/home NODUMP dump /usr/home
