We know the flexibility that we get out of OSGI container where we can edit values and those values are saved immediately. The next request starts picking up the values that the sys admin just put in.
The values are stored under /crx-quickstart/config directory. Basically osgi will find out the PID of the class/bundle and creates directories within the config directories.
So for example, Login Authentication Handler the values are stored under com/day/cq/auth/impl/LoginSelectorHandler.config.
If you change the value in the server itself the values are not picked up by the OSGI container, you have to do a restart if you want OSGI to pick up the values that you have change manually.
