It seems that shutdown from within GNOME is blocked by selinux-policy 88, with lots of these in ~/.xsession-errors: gnome-session[1429]: WARNING: Unable to stop system: GDBus.Error:org.freedesktop.DBus.Error.AccessDenied: An SELinux policy prevents this sender from sending this message to this recipient, 0 matched rules; type="method_call", sender=":1.5" (uid=0 pid=730 comm="/usr/lib/systemd/systemd-logind ") interface="org.freedesktop.PolicyKit1.Authority" member="CheckAuthorization" error name="(unset)" requested_reply="0" destination="org.freedesktop.PolicyKit1" (uid=0 pid=806 comm="/usr/libexec/polkit-1/polkitd --no-debug ") shutting down from a console works, and shutting down in permissive mode works. selinux-policy 89 seems to resolve this, but I couldn't find an associated bug, and it hasn't been submitted as an update. So I'm filing a bug for the purposes of blocker/NTH tracking, and to ensure 89 gets submitted as an update. This isn't Alpha blocking, per the criteria - we specifically require console shutdown to work, not desktop environment-triggered shutdown. But I'm proposing it as NTH, as it has an obvious impact and affects lives so cannot be entirely fixed with an update.
Dan, Miroslav - can one of you please submit selinux-policy-3.10.0-89.fc17 as an update? Thanks.
I hit the same issue on a fully updated F17 RC2 install. Installing selinux-policy-3.10.0-89.fc17 from koji fixes the problem for me. +1 NTH - While it's not a blocker, it's a highly visible and annoying bug.
