I've been fighting with this problem for more than 1 hour and I have no idea what's going on.Installation: $ sudo apt-get install supervisorVersion: 3.0a8-1.1+deb7u1$ sudo update-rc.d supervisor defaults$ reboot$ sudo service supervisor statussupervisord is  not running.pid and socket are not created.I manually try sudo service supervisor start/stop/restart and everything works...here is the default init script. Also, I simply run sudo grep -ri 'supervisor' in /var/log and can't find anything startup error.
