Hi folks,
after upgrading a Centos container (LXC) from 7.4 to 7.5 I got
this:
# systemctl status
Failed to get D-Bus connection: Connection refused
# busctl
Failed to connect to bus: Connection refused
# ps -ef | grep db[u]s
dbus 55 1 0 Jul02 ? 00:00:00 /usr/bin/dbus-daemon --system --address=systemd: --nofork --nopidfile --systemd-activation

Please note the "/run/dbus/system_bus_socket". AFAICT thats new. Shouldn't it listen
on /var/run/dbus/system_bus_socket for backward compatibility as well?
Is there is a way to fix this? Every helpful comment is highly appreciated.
