I don't think we need a separate virtual server for it.  At least not
yet.  I set it up here.

  http://mgt.savannah.gnu.org/munin/

The advantage to a separate URL though is that the service could be
moved from node to node without external disruption.

Except that there appears to be firewall blocking between mgt and all
of vcs, frontend, download.  It can only connect to internal.

I didn't start out with the idea that we needed to monitor performance
data.  I started out thinking that dpkg and apt should not produce
errors when installing additional tools on the machine.  So I wanted
to fix that problem throughout.

But munin itself appears to have been broken since 2009.  So I wanted
to either have it work or to uninstall it entirely.  I don't feel
strongly either way.

But I do like munin and use it myself on my machines.  Therefore I am
inclined to make it work.  Monitoring and historical data is one of
those things that becomes useful later when you unexpectedly have a
reason to go look at it.

Yep!
