snowflake-01: Reboot

In order to restart dbus, a reboot might be the best option.

Service restarts being deferred:
 /etc/needrestart/restart.d/dbus.service

LMK if you think there are better ways. Note that we lack all OOB on this server (like IPMI, ILO access), so we really don't want to mess up.

I'm planning on doing the reboot in connection to #40186 (closed).
