[Bug 1415514] Re: No /dev/uinput and Upstart cannot be contacted

[Martin Pitt]

It seems the main problem here is that this command in the setup script
fails now in current vivid:

   echo DBUS_SESSION_BUS_ADDRESS=\$(initctl --user get-env
DBUS_SESSION_BUS_ADDRESS)

gives

   initctl: Unknown job: rc

It seems something in upstart changed recently that now causes a new env
variable $UPSTART_JOBS to creep into the session environment which
breaks initctl --user.
