Added instructions for creating a passphraseless v2 RSA keypair for root
on boss, and explained where it needed to be added (on ops, boss and images).
Also described how to set Procotol 2 as the default everywhere possible.
THere is also a note about old user images and compatibility.

For boss and ops:
You must setup a new passphraseless keypair for root on boss.
To do this, simply run the following command on boss:
sudo /usr/bin/ssh-keygen -t rsa -N ""
Next, append the contents of /root/.ssh/ on boss to
the /root/.ssh/authorized_keys file on both your ops and boss
nodes. Remove any ssh version 1 keys that appear in either
of these authorized_keys files. Also, remove the
authorized_keys2 file (if it exists) from the /root/.ssh
directory on boss and ops. Next, change the
/etc/ssh/sshd_config (sshd config) file on both boss and ops
to try ssh protocol 2 first: Edit the line that reads
"Protocol 1,2" to be "Procotol 2,1".
For your default disk images:
Add the contents of /root/.ssh/ on your boss node
to the /root/.ssh/authorized_keys file in each of your
default disk images. Remove any version 1 ssh keys that
remain in authorized_keys. Also, remove any authorized_keys2
file that might exist in the /root/.ssh directory. Next,
edit the /etc/ssh/sshd_config file, changing the "Procotol
1,2" line to "Protocol 2,1". Re-create the modified images
(of course).
Note on user disk images:
User images may still require access via ssh version 1, so
don't delete the ssh version 1 key on your boss node
(/root/.ssh/identity[.pub]). The ssh wrapper command (sshtb)
has been modified to try authenticating with both ssh protocols
to preserve backward compatibility with existing user images.
