While it's essential for geoserver to have correct permissions to function properly. This introduces a real delay in the startup of those applications when the folder for geodata is big.

We should remove this initcontainer, instead have a cronjob that can be deactivated or activated. This way, the ones that want to keep this permission fixing behavior can do so.
