I've read the above a couple of times, and I'm still trying to make
sure I understand;  You're modifying the config files on disk, then
calling rescan and expecting them to be re-read?  If I have that
right, that's not how that works, and would be undefined behavior even
if it did work.  Entity-manager is expecting that the config files are
fixed for the lifetime of a service.  If you're doing this for testing
purposes, a simple systemctl restart entitymanager.service would
reload the files from disk and reinit all configurations, but as a
matter of practice, a system should not be modifying the config files
at runtime.  If you need that behavior, use the dbus interfaces to
modify parameters on dbus, and entity-manager will persist them for
