I'd like to have mirmon running as a first step. it won't help if rsync
fails in the middle but at least it will give us an hint of the health of
the mirrors.
Failing in the middle could be solved by moving to a 2-step rsync: first
all but a file with a timestamp and the last one only the timestamp, but
I agree that partial monitoring is better than no monitoring.
