How to override logging configuration in fabric child container ?

Issue

• We have changed the fabric/import/fabric/profiles/karaf.profile/org.ops4j.logging.properties file to customize the logging parameters, however, when we use container-create-child with the default.profile or the karaf profile, it is not using our customized logging properties.

• We see that the child instance file, /etc/org.ops4j.pax.logging.cfg file does not have our customized content and the data/log files are written using the properties from the logging.cfg file. How can we customize the child container logging properties? Looking at the child container's logging configuration in the FMC OSGi/Configuration tab for Logging /org.ops4j.pax.logging shows the same as the file contents - it does not reflect the customizations
