Looks like I missed a halt statement. I just added the code.
In the meantime, do this.
Boot to single user.
run /etc/rc.conf_mount_rw
cd /cf/conf/backup
Find the most recent file then issue:
mv $mostrecentfile /cf/conf/config.xml
run /etc/rc.conf_mount_ro && shutdown -r now
Replace $mostrecentfile with the filename that you found.
This will get you back up and running.
