[Bug 1562784] [NEW] cloud-init 0.7.7~bzr1189-0ubuntu1kills snappy boot

[Oliver Grawert]

Public bug reported:

the recent cloud init changes in version 0.7.7~bzr1189-0ubuntu1
completely kill the snappy boot on non-networked systems (leaving the
console with an unlimited systemd wait process) and cause a python
traceback on networked ones (there the boot finishes)

traceback:
