Hi ASX,
Sorry for my late reply I was away last weekend.
It's the same after editing rc.conf
I can't reboot because I'm in live mode and if I reboot I think to lose all configuration.Isn't it?
I think that "Questo matrimonio non sa da fare" (literally translated in "This marriage does not know how to do it") like in the The Betrothed
