[Scott Moser (smoser)]

The issue here is that ensemble launches instances with no public key (euca-run-instances --key).
fix coming.

[Scott Moser (smoser)]

This should be fixed in 0.23-0ubuntu4.

[Clint Byrum (clint-fewbar)]

So this still affects spawning lucid thru natty... marking Confirmed in juju.

[Kapil Thangavelu (hazmat)]

i'd rather not grow unesc. things in juju because of a historical bug in a third party package. i think this is a won't fix issue.
