linino bootup suggestion

The Yun has been rock-solid so far...

But should you ever mess with the linux side of the board, first thing I suggest to do is to upload the sketch found into Examples > Bridge > YunSerialTerminal.

The arduino side will became a serial terminal so just connect to USB (and open a serial term) to read the linino boot process and fix issues.

An invaluable tool IMHO.

Cheers.

scrap this!!!

there's a much better solution that doesn't involve scrapping your precious arduino sketch here http://forum.arduino.cc//index.php?topic=193038.msg1426864#msg1426864.

tried and true, it could be a very useful diagnostic tool, especially for wifi related issues.
