Robert Nelson pointed out that the issue blocking wifi is connmand, and not 
systemd/rfkill.  I've fixed that but have run into another issue.  Wifi 
starts, associates and grabs a DHCP address during init.  While init is 
coming up, wifi closes the association, and re-starts, but without 
association, and without DHCP. (log below).  systemctl --failed shows 
connmand-wait-online failed (log below init log).  Any idea why wifi is 
associating, and then dropping seconds later?
