I have upgraded MiniMyth2 to latest build via pacman, there was one 
error reported (does not seem significant as frontend works):

Same upnp problems exist with "Loading..." being displayed. Occasionally 
mythbackend is found but after Save it just hangs.
With the "Loading..." problem if backend is not found after few reboots, 
I just put a config.xml file in /home/mythtv/.mythtv/

I was aware of the recent breakage of upnp, but my backends are at 
MythTV Version : v30-Pre-333-g67a11c1 which is latest master as of writing.

I also rechecked the defaults for the mythfrontend  by changing the 
hostname (hostnamectl set-hostname <new hostname>)  and then rebooting.
I needed to use SetupWizard to change to OpenMAX:hdmi etc and the Audio 
Mixer.
The mythbackend provides default data to the frontend using hostname 
only, so if you already have a hostname of rpi2 in the mythconverg 
database those values will be used.
