Scrolling a couple of pages backwards, you suddenly realize that it was 
I who first mentioned the role of portaudit in maintaining the security 
info in this "thread". Nevermind.

There _might_ be a problem if one always upgrades to a newer release, 
this way or another, right on the production machine. The whole point of 
security updates is making users' lives easier. You upgrade, you want 
the software-OS bundle to behave, feel and touch _exactly_ the same way 
it did before. Once again, FreeBSD already _does_ that to the base system.
