Yup, that would be cool. However, on flash-based systems in the ARM926 / 200...400 MHz class (which is still quite common) the boot time up to the point where the penguin appears is still about 3...4 s [1] which is too long. So I suspect until systems become faster, we'll have no other choice than such as scenario. rsc [1] we can do some benchmarking next week -- Pengutronix e.K. | | Industrial Linux Solutions | http://www.pengutronix.de/ | Peiner Str. 6-8, 31137 Hildesheim, Germany | Phone: +49-5121-206917-0 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 | -- To unsubscribe from this list: send the line "unsubscribe linux-embedded" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
