$HOME=/root should be set only when you ssh to the device. On QtMoko runtime 
it's changed to /home/root. This is done in /opt/qtmoko/qpe.env which is 
sourced by /opt/qtmoko/qpe.sh which lauches qtmoko binary (qpe).

So now i wonder how it could have started working :) Did it start working from 
the gui or you launched the script from ssh?

Btw i was running for some time qtmoko with symlink /root -> /home/root and it 
worked well. I quite dont understand the /root and /home/root separation - 
what is it good for...

Hmm i think QtMoko does not touch wifi rfkill. Maybe it should start using it, 
but maybe it's not needed. We would have to check if kernel shuts wifi power 
automatically when the interface is down - i guess it does.
