[dbus] /etc/machine-id does not exist
After grabbing dbus from packages, /etc/machine-id is not created. I wasn't able to track down which package/component exactly should be responsible for this file, but dbus won't do anything without it present and filled. It's easy enough to fill it with 32 zeros, but having a "real" id generated automatically would be nice.
The man page for /etc/machine-id isn't very useful either: https://www.freedesktop.org/software/systemd/man/machine-id.html
