Why are we using cron jobs for the regularly to do things, that last
long!? It's very difficult to put them at the right time so that they
aren't conflicting. Why aren't we using one shell script that runs
these jobs one after another. So master has only to work on one big
job. This should reduce the normal load of the machine *and* each job
will be done faster as the machine isn't switching between processes
that are using the same resources like the hard disc. The simultaneous
usage kills all caching and other tuning mechanism.
I like the idea of reducing masters load by providing a more tree like
mirror architecture.

Can't we use some of out donations to give this machine more disk
space. Up to date mirrors are IMHO important for Debian.
