57 servers around the world that I have to maintain, patch and upgrade
at the same time as devel and maintain my applications... yeah I don't
do source stuff ;-)

It would be useful to have that option in freebsd-update.

Not clean and very error prone... replace base was a lot cleaner and
less error prone... but then you never know the people in security might
surprise us and put out a version of base with openssl 1.0.2b in it -
this would be a real bonus for a lot of people and take us a little bit
away from debian where you can wait months/years for an update.... and
then sometimes only if you upgrade your system to include features that
you don't want.
