Comment 12 for bug 1952763

Dropping my comments from #ubuntu-release in here for posterity:

RAOF: Oh! I think I see where I'm wrong. /etc/manila/policy.json isn't shipped in the package, it's /usr/share/manila-common/manila.conf which is then munged into /etc/manila/policy.json by pkgos_write_new_conf in the postinst, so it's not a dpkg conffile and so you don't have all that nice machinery available.

RAOF: So, in summary: the package in impish-proposed fixes fresh installs of manila, leaves upgrades broken, and unbreaking upgrades is not trivial.

RAOF: Based on that understanding I'm happy to accept what's in the impish queue as an SRU. You're going to need to fix it in the openstack charm anyway, though, so if you don't want that SRU to go through I'm also happy to reject it ;)
