Hm, that sounds like a bug in systemd or in some other component that it
calls during "systemctl enable networking.service". Marco, can you see
from your strace logs what process did that dbus call?
The current version of ifupdown calls systemctl from postinst "by hand",
but the next version will use dh-systemd, maybe that will fix this issue
as well, but I'm not sure.
