Some may call me careless, but on machines I update via source compiled
on themself I do:

 - depending on age of the running system: build.sh -o -t (skip thist step
   if the tools are there and not too old)
 - build a kernel
 - boot the kernel
 - build.sh -o

The last step will end with a run of "postinstall check", if that notes any
errors or differences, I'll add

 - run "etc/postinstall fix"
 - run "etc/postinstall check"

and repeat (with possible manual interactions) until there are no more errors.

This works pretty good for me, I even used this method on a production server
running (until then) 1.5.3_xxx - it was the smoothest update from one release
to the next I've ever seen! Thanks for postinstall, it rocks!
