Open Stack

Hi,

As I am slowing fixing all systemd issues for the daemons of OpenStack
in Debian (and hopefully, have this ready before the freeze of Jessie),
I was wondering what kind of Type= directive to put on the systemd
.service files. I have noticed that in Fedora, there's Type=notify. So
my question is:

Do all OpenStack daemons, as a rule, support the DBus sd_notify thing?
Should I always use Type=notify for systemd .service files? Can this be
called a general rule with no exception?

Cheers,
