Argh.  And I suppose there is no way to promote the Samba instance; or  
some way to force the samba upgrade script to create a DC?

My imported smb.conf had -
   domain master = yes
   domain logons = yes

I suppose this is revealed in that testparm  says "Server role:  
ROLE_STANDALONE"

barbel:~ # testparm
