The configuration files (glance-api.conf, glance-cache.conf, glance-registry.conf etc) are currently manually synced with the options defined in the code. This is causing an unnecessary amount of contributor's effort to maintain, especially when we can automatically keep them up to date using oslo-config-generator. They have also not been correctly updated in the past; glance-cache.conf does not have any of the deprecated glance store options marked as such, for example.
A slight complication is some options currently have better documentation in the example config files, rather than the help text defined in the oslo.config option (example on current master: [DEFAULT]/property_protection_file). These options should be updated with the better documentation before automatic syncing takes place.
this bug has no progress for over 5 months, I will take it since there already has a patch for it, see https:/
