Seems alright if I just launch an instance. Also inside the juju
bootstrapped containers you can see some ssh related stuff where it sets
keys etc in the logs so its logging in and doing something.

I've compiled everything from 1.26 alpha2 to master so I'll happily wipe it
clean and try the branch! ;)
