The named initscript checks the existence of rndc.key file
on the server start-up.
User having a custom rndc configuration may include a key from a file located in other than the default place. In such situation the initsctipt generates a rndc.key in the default location even if it is not needed and used.
The initscript was fixed to check for include statement with "rndc.key" in the rndc configuration before generating the rndc.key file.
As a result, if user has a custom rndc configuration including a rndc.key file from other than the default location, then the initscript will not generate a rndc.key file in the default location during the server start-up
