If you are short on disk space then from what I can tell it seems to
be harmless to erase everything under /var/db/freebsd-update before
you run "freebsd-update -r x.x-RELEASE upgrade". The catch is that
you lose the ability to use the "freebsd-update rollback" command.
After all, /var/db/freebsd-update/ presumably begins life as an empty
folder after an initial install of FreeBSD.
That is my experience, anyway. I may be wrong!
I assume the way "rollback" works is that if you use freebsd-upgrade
to upgrade from 6.2-REL to 6.3-REL, then again to 6.4-REL, the theory
is that you can reverse the upgrades all the way back to 6.2-REL
again. Whether you'd actually want to do that... I'm not sure. It
seems to me that if you upgraded to 6.4-REL, then you'd probably only
ever want to rollback as far back as 6.3-REL. I guess the ability to
rollback multiple releases is provided mostly because it's possible,
and disk space is cheap.
I suppose you could always create a symlink:
mv /var/db/freebsd-update /var/db/freebsd-update.old
ln -s /disk/with/lots/of/space/freebsd-update /var/db/freebsd-update
