This resembles linux RPMs for system files. And the idea is not
bad. Having system files registered just like ports would make it
easier some operations, including binary upgrade. I think the ports
system needs some work before this would be feasible, though.
IIRC, Solaris also registers system files with the same mechanism
used for applications.

I think the problem deserves attention, and any implementation
tests are welcome.
