The main problem with running mythtv-setup as a user other than the one 
that runs mythbackend is that some files get written with wrong 
permissions and/or the user doesn't have access to the Storage Group 
directories and users get warnings (that confuse them).

Showing people how to properly use xauth (or even set XAUTHORITY--which 
shouldn't work, anyway, due to home directory permissions) isn't 
something I want to try to do in a "simple" upgrade instruction.  And we 
shouldn't recommend using something awful like xhost +.  Perhaps sux is 
the best thing to recommend.
