filesystem_store_datadir doesn't have the default it pretends

[Thomas Goirand]

Testing Glance Liberty RC1 over on top of Jessie, I have found out that if I don't write a value for filesystem_store_datadir in both glance-api.conf and glance-registry.conf, Glance simply doesn't work, despite what is written here:

http://docs.openstack.org/developer/glance/configuring.html#configuring-the-filesystem-storage-backend

So I would suggest to either fix the doc, or better, make it so that the filesystem_store_datadir really defaults to a sane value, which is /var/lib/glance/images in the case of a distribution deployment. It is my understanding that devstack anyway sets a correct value there, so we wont break the gate by fixing the default value to something that works.

Hoping this helps.

    Set documented default directory for filesystem

    We document that the default value of filesystem_store_datadir is
    /var/lib/glance/images without ever actually setting that default.
