Mike,
Thanks. We are doing the same thing in our earlier version of the cluster,
and I may do it again.
That approach only gets me halfway there, though; I still have to find a
way to automatically create an SSH key pair for each user, and copy the
public key to the authorized keys file. And I have to find a way to
generate the known_hosts file. Both are easily doable, of course; I was
just wondering if xCAT had a built-in way to do it for me.
