Drivers and networking account for about 50% of the total lines of code. The bulk of the work in any operating system is typically drivers. The generic part of Linux (non-driver, non-file system) is tiny compared to the rest. If the Hurd gets its drivers from Linux then it should rightfully be called Linux/HURD (or Linux/HURD/GNU). work /tmp/linux-2.5$ bk -rnet cat | wc -l 326411 work /tmp/linux-2.5$ bk -rdrivers cat | wc -l 2605850 work /tmp/linux-2.5$ bk -r cat | wc -l 6618524 -- --- Larry McVoy lm at bitmover.com http://www.bitmover.com/lm - 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/
