Description of problem:


When restarting, there is a 1m30s hang, and the journal reports that the gdm user session was not killed until the 1m30s delay elapses.


Version-Release number of selected component (if applicable):
systemd-229-8.fc24.x86_64

How reproducible:
Always



Steps to Reproduce:
1. /etc/systemd/logind.conf KillUserProcesses=yes and uncommented, system rebooted.
2. sudo restart or via gnome-shell power button UI to restart


Actual results:

1m30s delay

Expected results:

Should kill the gdm user session so reboot can happen pretty much right away.

                                    If you want to fix the label. 
                                    /dev/shm/lldpad.state default label should be lldpad_tmpfs_t.
                                    Then you can run restorecon.
                                    Do
                                    # /sbin/restorecon -v /dev/shm/lldpad.state

                                    If you believe that systemd-logind should be allowed getattr access on the lldpad.state file by default.
                                    Then you should report this as a bug.
                                    You can generate a local policy module to allow this access.
                                    Do
                                    allow this access for now by executing:
                                    # ausearch -c 'systemd-logind' --raw | audit2allow -M my-systemdlogind
