I think having this command run at install time was just a convenience 
to configure the DHCP.  IIRC it was created mostly to mimic what cobbler 
does.

I don't really why having two different workers will help here.  The 
master worker (in charge of DNS) will simply receive all the tasks that 
have to deal with DNS.  Can you expand on why having two workers will help?

That sounds reasonable to me, and doable by simply skipping the call to 
"maas config_master_dhcp" but again, I don't see why having different 
workers will help.

Looks good to me but can you elaborate on what maas-dns would contain?
