Copy the two ndz files to someplace on the public network that you can get
to with http or ftp (from the control node being rebuilt).
Might be a good idea to delete the file from /tmp since it has a password
in it. But make sure you have stored a copy someplace safe and encrypted to
be safe.
Also copy /var/tmp/boot.sdb from the Utah control node to the control

Save the old boot blocks someplace safe (on another machine):

Grab the first part of new MBR (see above):

* Now upgrade the control node to Ubuntu14:
