[mirror-admin] master server sync stats and recommendations

[Günther Fischer]

For me - the best way would be:
   * fedora/redhat give a script to the mirrors (perl, python or bash)
and also an rsyncd.conf with actual accesslists
      * Tier 0/1 must use this scripts and gives to the T0/1 exclusive
access to some masters
      * other mirrors can only use T0/1 - some T0/1 can be the on the
master side
         * all can use every T0/1 without local agreements
   * regional dns names for the T0/1 could be helpful

Mit freundlichen Grüßen / Regards
Günther Fischer
