[Xfce-bugs] [Bug 14722] Better shutdown fallback code for the BSDs

--- Comment #19 from Landry Breuil <landry at xfce.org> ---
ok, first i looked and tried hard to understand the existing xfce4-session 4.12
code flow without patches, here on OpenBSD, and those are my findings:

- if :
  - messagebus/systemwide dbus is running
  - the session is launched within consolekit
  - polkit is running
  - but we're not in operator group

in the logout dialog, all actions are available.

- the shutdown code tries to go via consolekit_try_shutdown, but the default
consolekit rules on OpenBSD
(http://cvsweb.openbsd.org/cgi-bin/cvsweb/ports/sysutils/consolekit/files/10-openbsd-consolekit.rules?rev=1.2&content-type=text/x-cvsweb-markup)
require operator group to shutdown, or would ask for auth - i dont have a
polkit agent installed, so the ckit codepath fails, doesnt ask for a passwd
(apparently, even with mate-polkit installed it fails)
- the fallback code 'works' because the polkit rule installed by xfce4-session
in polkit-1/actions/org.xfce.session.policy allows the active session
(<allow_active>yes</allow_active>) to execute xfsm-shutdown-helper (via
consolekit, which runs as root) so a regular user (not in the operator group)
is allowed to shutdown/reboot.

now, to look again at that new fallback code....
