Portupgrade

[Stefan Malte Schumacher]

Hi

I have just run portupgrade -a for the first time. About 2 hours later I
realized that portupgrade is not only building the port I built myself from
/usr/ports but also the packages which I did install from the CD. I do not
want to build Mozilla or XFree myself, is there a way I can exclude such
large programs from being updated ? Are installed ports and packages stored
in the same database ?

For the next question I just need a pointer to the right documentation ; 
I would like to read more about using sysinstall to upgrade my system
instead of "make world." 

Is there some kind of "packageupgrade" which downloads and installs new
packages for stuff I do not want to build myself ? 


Bye
Stefan
