Hi there,
Please note that I have installed a clean Xen domU VM to better test this issue
and potentially report a bug. One difference I noticed is that
DBUS_SESSION_BUS_ADDRESS is not defined in permissive or enforcing modes in
this clean install. However the systemd --user unit works in permissive mode.
Here are my findings:
SELinux permissive
