Postfix has the command postconf which prints the entire Postfix configuration including its default values (default can also be shown using the -d option).
Samba has a similar command which prints the entire configuration file including its default values: testparm -v.
I'm however unable to find a similar command to print the entire configuration BIND file including its default values. I know I can look up the default values in the BIND9 Configuration Reference (Chapter 6 of the ARM) but this is tedious and the default are not easily spotted when skimming through the web page. Does this option exist for BIND?
