We are looking to get two or three syncmasters in the european region,
out of these only one should rsync from auric and send out triggers
to the tier1 european mirrors.

The system should still work if one server fails and doesn't update or is
unreachable. This means that every syncmaster server needs to get a trigger
from auric and have a way of determining if it should initiate a sync
or wait for another syncmaster to do the job.

The syncmasters also needs to be able to trigger the european tier1 mirrors
and have them update the archive from the syncmaster that actually has the
updated archive. 

The issue on how to update and what server to update from is pretty much
solved, pipe the hostname to the ssh and it will get to the other side. It is
then up to the script to read it securely.  Adam is working on this.
