 * document in the initial webpage, that we don't have a clear idea yet, how to record+reproduce the build environment. +that this is essential for reproducible builds too.

+----
+* use regular maintenace job to update the arch schroot
 * create another job, to build a single package and a webpage for it…
 * create a simple scheduler and build a few more packages…
+** schroot, find packages in /var/abs/core/, schedule those
+*** idea: reschedule reverse build depends too
