Cool, didn't know that keystone supports the systemd notification
protocol. We should definitely use that post jessie then. Do you know if
all the openstack daemons support this and configure it in the same way?

That looks like a good solution to me to get rid of the /etc/default
files without loosing any functionality. This would avoid duplicating
configuration settings in configuration files and /etc/default files.
Looks like the best solution to me, but ovviously post jessie.
