I've had Enterprise systems where I could hit power on two boxes, and finish the OS install on one before the other has even finished POST and look for the boot media. I did this 5 years ago, before the "let's speed up boot" push started. Admittedly, this wasn't a stock distro boot/install, it was my own optimized one, but it also wasn't as optimized and automated as it could have been (several points where the installer needed to pick items from a menu and enter values) David Lang -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
