Dashboard should not add WSGI config in /etc/apache2/conf.d

[Andrew Glen-Young]

The dashboard should not add WSGI config in /etc/apache2/conf.d providing a _global_ configuration change. This breaks all the other VirtualHosts on the Apache server.

I had a previously defined VirtualHost which served the dashboard. The package installation failed during upgrade because Apache's config was incorrect.

Error during upgrade:

Setting up openstack-dashboard (2012.2-0ubuntu1~cloud0) ...
Syntax error on line 28 of /etc/apache2/sites-enabled/dashboard.canonistack.canonical.com:

Status changed to 'Confirmed' because the bug affects multiple users.

consider to write one like the Debian one

<VirtualHost *:8080>
    WSGIScriptAlias / /usr/share/openstack-dashboard/openstack_dashboard/wsgi/django.wsgi
    WSGIDaemonProcess openstack-dashboard user=horizon group=horizon
    WSGIProcessGroup openstack-dashboard

    <Directory />
        AllowOverride None
    </Directory>

    <Directory /usr/share/openstack-dashboard/openstack_dashboard/wsgi/>
        Order allow,deny
        Allow from all
    </Directory>

    Alias /static/horizon /usr/share/pyshared/horizon/static/horizon

Hi, is there any way to fix it?
I couldn't remove the "haft-installed" package.
