[Bug 1285765] [NEW] havana openstack-dashboard from UCA enforces /etc/apache2/conf.d/openstack-dashboard.conf symlink

[James Troup]

Public bug reported:

After installing the openstack-dashboard from the Havana pocket of the
UCA on Ubuntu 12.04, I removed the
/etc/apache2/conf.d/openstack-dashboard.conf symlink in favour of our
local/custom config in
/etc/apache2/sites-{available,enabled}/$HOSTNAME as is our site/normal
practice.

On upgrade the openstack-dashboard re-added the symlink which caused
conflicting WSGI Process Groups and apache to fail to start, which in
turn caused the package upgrade to fail.

I then tried removing both
/etc/apache2/conf-available/openstack-dashboard.conf and
/etc/apache2/conf.d/openstack-dashboard.conf but the upgrade still
added a dangling symlink in
/etc/apache2/conf.d/openstack-dashboard.conf.

Eventually I was able to unbreak the upgrade by re-adding
/etc/apache2/conf-available/openstack-dashboard.conf but making it
empty.

I believe if either:

 a) /etc/apache2/conf-available/openstack-dashboard.conf has been
    removed by the administrator

 and/or

 b) /etc/apache2/conf.d/openstack-dashboard.conf has been removed by
    the administrator

then the package postinst should not re-add the
conf.d/openstack-dashboard.conf symlink.
