I upgrade systems by creating packages which contain all upgraded files
I have a set of makefiles etc. checked into my local CVS tree that check out
a freeBSD tree at a given revision and build it (withlocal patches added)
and then extracts out fies according to a list I supply. On completion I check 
the list in too, so I can theoretically recreate that patch..

I use the package system to keep track of which packages are loaded onto a 
system, and newer upgrade packages always have earlier ones as dependencies..
