Silence the setting up of the socket. This was appearing whenever you started a new tty.js terminal - leaking stuff that shouldn't really be. 2014-08-19 17:46:38 +01:00			`#!/bin/bash`
Enable spawning a tty.js tunnel. 2014-08-04 12:10:36 +01:00			`SOCKET_NAME=test-${1}-${2}-${3}`

Make sure that the command socket exists and is a socket. This handles the case of running an updated supervisor on an old image which doesn't support host commands - printing out a nice message and waiting rather than exiting silently. 2014-08-19 18:09:19 +01:00			`COMMAND_SOCKET=${SUPERVISOR_SOCKET_PATH}/host`
