Once installed, all masters are identical (except some might have a CA 
and some not).
The distinction is useful when installing a replica, where "master" and 
"replica" generally mean "existing master" and "new master", respectively.

Yes, you're creating a new master; since you gave --setup-ca the two 
masters will be equivalent.
