Current docker-machine AWS driver creates Ubuntu 15.01 VMs. Looking at the sources docs it seems that next release will create Ubuntu 16.04 LTS.
Trying to change the ami image makes docker-machine hang on SSH connection:
➜ ethereum git:(master) docker-machine create --driver amazonec2 \
--amazonec2-region us-east-1 \
--amazonec2-zone b \
--amazonec2-instance-type t2.nano \
--amazonec2-ssh-user etheruser \
--amazonec2-ami ami-c60b90d1 \
--amazonec2-ssh-keypath ~/.ssh/id_rsa \
etherplay-1

Error creating machine: Error detecting OS: Too many retries waiting for SSH to be available. Last error: Maximum number of retries (60) exceeded
I will try to use a nightly build of docker-machine. Is there any place to download a nightly release or must I build it myself?
Tnx!
