[Rdo-list] [OpenStack-docs] [install-guide] Status of RDO

I think distribution packages should bundle upstream source without
alteration to maximize flexibility for authors of deployment tools (or
simple instructions) that choose to use packages. In other words,
distribution packages should include few if any decisions on how to deploy
services. Instead, leave those decisions to authors of deployment tools
including organizations that produce distribution packages. For example,
decisions on how to deploy OpenStack using RDO packages should reside in
products like Packstack and RHEL-OSP. In the meantime, content in
/usr/share/$service directories impacts the following portions in the
installation guide:

1) http://docs.openstack.org/draft/install-guide-rdo/keystone-verify.html -
The keystone-paste.ini file should reside in the /etc/keystone directory.

2) http://docs.openstack.org/draft/install-guide-rdo/glance.html - The
glance-api-dist.conf and glance-registry-dist.conf files contain defunct
options in the [keystone_authtoken] section. Also, the *-paste.ini files
should reside in the /etc/glance directory.

3) http://docs.openstack.org/draft/install-guide-rdo/nova.html - The
nova-dist.conf file contains defunct options in the [keystone_authtoken]
section, assumes use of nova-network, and contains several opinions about
libvirt configuration.

4) http://docs.openstack.org/draft/install-guide-rdo/neutron.html - The
neutron-dist.conf file specifies a notification driver regardless of a
consumer (e.g., ceilometer) and disables nova-neutron interaction. Also,
the *-paste.ini file should reside in the /etc/neutron directory.

5) http://docs.openstack.org/draft/install-guide-rdo/cinder.html - The
cinder-dist.conf file contains defunct options in the [keystone_authtoken]
section. Interestingly, the *-paste.ini files correctly reside in the
/etc/cinder directory.

6) http://docs.openstack.org/draft/install-guide-rdo/swift.html -
Interestingly, no /usr/share/swift directory exists. However, the
configuration files in /etc/swift are considerably out of date and easier
to overwrite from upstream source than attempt to fix via procedure.

7) http://docs.openstack.org/draft/install-guide-rdo/heat.html - The
heat-dist.conf file contains defunct options in the [keystone_authtoken]
section, contains a defunct database connection option (belongs in
[database]), and enables a defunct message queue (Qpid). Also, the
*-paste.ini file should reside in the /etc/heat directory.

I haven't looked at the ceilometer packages recently, but I suspect they
involve similar issues.
