/mit/jrjarvis/Public/athena-auto-upgrade
Went with the grub-reboot approach and put the kernel/initrd on athena-
root.
Creates a new entry in grub.d for "auto-upgrade", modifies
/etc/default/grub, grub-reboots into auto-upgrade to kick off the
installer.

Note if something does fail during upgrade /etc/default/grub will be
tainted.
