Hi Joseph,
Have you checked to see if your oscarimage(e.g.,
/var/lib/systemimager/images/oscarimage) has the same "root/.ssh" as the one of
your head node?
And please make sure authorized_keys{,2} are properly setup too.
If it is not setup properly, the password access of root can not completed.
I don't know what happens to your installation but I have never seen this
problem on my default installation.
If you can provide some detail of your installation, I would like to reproduce
your problems and then look into them further.
Regards,
- DongInn
