the "install/uninstall" data, as you call it, is managed by the
installed packages, whose database is in /var/db/pkg, it doesn't even
read or touch /usr/ports

about your first question, i don't understand why you don't want to
update the whole tree. unless you want to be able to reinstall ports
at the same version they are at the moment (and then you really need
the current version of the Makefiles, or at least the built packages),
i'd update the whole tree and then update individual ports (and maybe
their dependency, when strictly required), keeping all the other
updates off

or did i completely misunderstand?
