cloudinit/config/cc_ssh.py : DISABLE_ROOT_OPTS = ... echo ... sleep 10
This gives zero exit code. Automated tools (like parallel-ssh) are mislead. Probably should be:
cloudinit/config/cc_ssh.py : DISABLE_ROOT_OPTS = ... echo ... sleep 10; exit 1

Thats an interesting suggestion.
I don't think there'd be any significant fallout of changing that in trunk.

fwiw, it is ocnfigurable, by setting 'disable_root_opts'
default value is:
DISABLE_ROOT_OPTS = ("no-port-forwarding,no-agent-forwarding,"
"no-X11-forwarding,command="echo 'Please login as the user \"$USER\" "
"rather than the user \"root\".';echo;sleep 10"")
