It's all up to the rules you are using for udev. If you have udev rules that call out to scripts for every device (like I think the SuSE default install does), udevstart can take a long time. If you don't have any external dependancies, udevstart is fast. > If its to be used, its got to speed itself up, a LOT!. Please post what version of udev you are using, and what your udev rules file looks like. thanks, greg k-h - 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/
