Well, if you can help figure out what is going wrong, then I'll fix that
in the images.  Just looking through code, I can't see what would be doing
it other than you passing a kernel command line option to your instances
of 'nosshd' .  But surely you'd know that.

There is a bug that I should fix where the image tries to figure out if
this is a slow system, and if so, it will not generate ssh keys.  clearly
you *always* want ssh keys generated if its your only access to the system
even if it takes a long time.

I can't imagine that this would be an issue.
Could you give a url to exactly what you're using as the ttylinux image?

I've recently been working on this some, and I plan to start making those
things with more sane version numbers than are present now.
the recent snapshots i have at
http://smoser.brickies.net/ubuntu/ttylinux-uec/dev/ support running under
nova-lxc also.
