Ian Wienand a5bd03ec6b journal-to-console: element to send systemd journal to console
This element configures systemd to send its journal to the console,
which can then be retreived by server commands.  In the case of
nodepool, if the image failed to boot the console will be dumped into
the logs when nodepool decides the node is not responding.  Having
this can be very helpful diagnosing early boot errors.
