# NOTE: due to stack creation issues on public cloud, installation of python
# and python-dev has been moved out of heat templates. The reason for this is
# that during initial boot of the instances, Ansible prerequisites python and
# python-dev are installed using boot script. Due to the reasons we can not
# explain and perhaps because of network issues on public cloud, apt fails,
# complaining about corruption - checksum mismatch. In turn, problematic
# instance(s) can not send completion signal at the end of boot phase, resulting
# in timeouts in stack creation thus complete failure of deployments.
