Ok, so we enable testing in /etc/pacman.conf to build alpha/beta isos
with the new kernel etc, then after testing etc, we get everything we
need from testing into core, and build iso's with core only.

Of course.  What I meant is just: instead of building locally and then
uploading, we could rebuild on gerolde and assume the iso over there
if the same as the one built locally (if we pay very close attention
to /etc/pacman.conf). I don't know what kind of connections you have,
but for me to upload several hundreds of MB would take a loong time. (my
upload is somewhere around 10-50kB/s)

This does not mean any change in testing procedures.
