I just figured this out myself. You have to runs ssh with flags "-t -t"
(or just "-tt"). That flag says to allocate a tty, but you need 2 to
force a tty when ssh is not called from a tty.
BUT, I also see that you are using "ssh -l root". The point of using
sudo is that you don't need remote-root access. The default
configuration needs to be better designed to get this right, with proper
security considerations.
Another problem I realized is that rsync cannot preserve user/group
values unless the local rsync is run as root.
I am going to try to work on this. Hasn't someone else on this list
worked on this??
