There's no way without using initramfs. Lilo only records the unix device number (like 8:1 for /dev/sda1) and passes it to kernel (replacing `current' with that number). But for different kernels (IDE vs PATA drivers) the number will be different. Lilo itself - when booting at least - can not know which device it will be. The only universal solution is to use smart initramfs that will populate /dev/disk/by-label/ etc (using udev maybe). Another solution is to explicitly specify root=/dev/sda1 or root=/dev/hda1 when using pata- or ide-enabled kernels, in lilo.conf. /mjt -- 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/
