Comment 1 for bug 1879072

Chris, it does seem that the charm doesn't handle the 'source' config param apart from during the installation. i.e. not on config-changed (afaict). It looks like the charm will need an update.

Notes:

The charm also doesn't use charms.openstack and instead uses layer-apt. We should give serious consideration to switching it over to charms.openstack so we can access all of the default behavour of upgrades, managed upgrades, pause/resume, SSL, space support, etc.
