How can be the b10-cmdctl listen address changed?

Yes, we don't currently offer a way to set command-line arguments using 
the Init startup. (Well I do see an undocumented "params"... I will 
send another email to dev list about that.)

This address is not the listening address used by cmdctl. It is the 
address used by the component on the b10-msgq message bus.
(Note it is an Init configuration.)

We don't have a Cmdctl/ configuration for the listen address yet.
A ticket for this work is http://bind10.isc.org/ticket/656

As a quick workaround, I suggest creating an executable shell script 
(let's call it b10-cmdctl-custom) which does: 
/usr/local/libexec/bind10/b10-cmdctl --address REPLACETHIS

Then override the program to run by setting
Init/components/b10-cmdctl/process to that script.
