Public bug reported:
A file that is commonly modified is /etc/environment.
If you remove the PATH line in this file, you can start a session upstart-less
quite easily, and things will still work.
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"
However, if upstart manage your session, you can't log in (you will be
rejected and going back to the greeter quickly). I thnk we should be
more fortified against this pebkac issue, especially has we have no
really good log for it to know what happened (nothing in lightdm or
upstart logs rather than exiting the session and gnome-session logs were
not there as it's not executed).
What happens is:
/usr/sbin/lightdm-session: 5: exec: init: not found
in .xsession-errors.
indeed, which init doesn't return anything as /sbin isn't in path. We
should maybe hardcode /sbin/init in this script?
