   ### Enabling ssh
   
   If you want to enable ssh with the standard image, so that you can log in over the net without either a serial or HDMI console, mount the ffs partition, place /root/.ssh/authorized_keys, uncomment PermitRootLogin in /etc/ssh/sshd_config, and comment out the rc_configure=NO in /etc/rc.conf.  Besides having to find the IP address, you will have to wait for the partition resizing and reboot.
