Do you mean all packages are rebuilt for each build?
I've done a distro here using much the same mechanism
as you describe above except it works from upstream
source packages and our diffs. Also it only builds what's
necessary. The logic quite simple and is essentially like:
./configure && make
while read package; do
if [ $PACKAGES_DIR/$packagefile -nt $packagedir ] ||
[ $PACKAGES_DIR/$packagedir.diff -nt $packagedir ]; then
echo "building $package..."
build_`echo $package | tr +- __` $packagedir </dev/null
echo "$package already built"

I think your talking about continuous integration here,
which is a buzz word comming mostly from the java community.
There is a nice comparison matrix here:
We use cruisecontrol here in corvil, but that is only for the java
side of things as essentially the whole java project is rebuilt
on each checkin. For the linux distribution build script I
outlined above, I've a cron job that calls that every night.

yes I thought that was interesting also.
There is an example of that at:
