No, we definitely do not want that. We are trying to split the jobs
up so the mirror load caused by update can be spread over the entire
day instead of occuring in a predictable interval. Otherwise the
(Ubuntu) mirrors overload and upgrades timeout (and running the
upgrades at a very random time causes very random system failures
if something goes wrong ;/).
