Backup ssh keys from your Joyent account to /root/.ssh/authorized_keys. Don't forget to change ACCOUNT, DC, and AUTHORIZED_KEYS. Schedule this via cron to always ensure you have a recent backup NOTE: this assumes you have smartdc (the latest 7.0 version) and jsontool installed (via npm): 'npm install smartdc -g; npm install jsontool -g`
