supervisord: error: <class 'socket.error'>
I can't get supervisord to work; after starting the process with:
# supervisord -n -c /etc/supervisord.conf
2013-05-29 11:34:11,861 CRIT Supervisor running as root (no user in config file)

Summary : A System for Allowing the Control of Process State on UNIX
Description :
The supervisor is a client/server system that allows its users to control a
number of processes on UNIX-like operating systems.
The problem was that the version was old and buggy:
I have upgraded this: https://github.com/haf/puppet-supervisor to install the latest version of supervisor.
The core problem seems to be that failure to launch the daemon the first time creates the socket file at the run location, but the initv script doesn't support removing it (so it must be done manually).
