Bug#763028: systemd-sysv shutdown and reboot hang system

[Martin Pitt]

Hello all,

Yesterday we found quite a fundamental flaw related to how D-Bus is
stopped during shutdown [1]. It might be worth a try to edit
/lib/systemd/system/dbus.service and append these two lines to the
[Service] section:

  ExecStop=/bin/true
  KillMode=none

Then run "systemctl daemon-reload" as root. Does this improve shutdown
for any of you?

Note that this is certainly not a magic bullet for all kinds of
shutdown problems, especially since the reports/data here is vague
enough that these might very well be different reasons. But it would
be interesting to see if it makes a difference for any of you. The
Ubuntu bug https://launchpad.net/bugs/1427672 was linked to this
Debian one and found to be fixed with the above D-Bus change.

Thanks,

Martin
