experimental, i don't know. i ve never installed more than a debian testing
version. unstable was always hard in my view, but experimental, is
definitively too hard for me... and i imagine there's no tutorial to do it,
or it is maybe very complex for someone who is not develloper.
anyway, if my pcduino3 can be useful for future debian tests, i can try
some things...
thanks,

Patrice G.
