Linux ServerWatch writes about the slow but sure death of UNIX by the onslaught of Linux and customers moving from older proprietary UNIX systems to commercially supported open source enterprise Linux distributions. "Linux does have one killer feature that is driving the switch: lower cost. Many companies are discovering Linux to be extremely attractive from a cost perspective. Take the experience of Sabre, a travel company that replaced Solaris with Red Hat Enterprise Linux (RHEL) running on x86 machines, resulting in lowering costs 90 percent (with a three-fold speed gain to boot). These potential cost savings, which include hardware maintenance costs savings, are not to sniffed at."

The Linux kernel now exceeds 10 millions lines of code, including comments, empty lines, etc.

If you only count source code, then Linux kernel is 6.4 million lines of code.


Don't get me wrong, please. I didn't want to focus on a kind of "BSD vs. Linux kernel documentation" approach. It's just about my individual observations, and it's far more than just kernel, or system. Have a look at "modern" applications like all the KDE stuff. Try to "man kde" (or a KDE related program), or try "man grip" (for a Gnome related one); in opposite, try "man opera" or choose some arbitrary kernel interface, library function or device driver. On a BSD system, you're usually lucky. Then, have a look at the system's source code (and not only the kernel one's): The source is very tidy and quite good to read. This is something I really applaud: Taking the time to document what's already working, instead of "just let it work and let others write some documentation on the Web".

I vaguely remember that entire Windows NT was 10 million lines of code? Is that correct?


I don't know about "Windows", I have none. :-)

Is linux kernel growing like mad? Is it difficult to have one monolithic kernel with 6.4 million lines of code bugg free? Hell yes. Is it not as stable as it could be? Yes.


I wouldn't try to say anything else. In regards of functionality, Linux has walked a long (and good) way to get POSIX and other compliances.

Thanks, very interesting!

Anyway, a kernel consisting of 6.4 million lines of code is too much. It should be stripped down.
