New Linux Kernel Configuration System
An anonymous reader writes "When Eric S. Raymond tried to replace the Linux kernel's configuration system with "something better", he got booed off the stage. Now Roman Zippel is bravely having his own go at it. Here's an interview with Roman and a look at his new configuration system, aimed for inclusion into the 2.5 development kernel. Also, find some screenshots of his new graphical configuration frontend."
- It required Python to build the kernel.
- It was complicated. It included an entire theorem prover. This was sort of cool in that it would not allow you to generate a non-working configuration, but really more than was required for the job.
- Its language was arcane. The main language idiom is the suppress-unless statement, which is sort of the logical negation of if-then statements.
- And some folks questioned his motivation for getting this grandiose project into the kernel - was it just to help out, or was it primarily to establish additional hacker reputation for Eric? I'd be willing to give him the benefit of the doubt on this - he did the work.
I think he had a chance of getting it in, but he would have had to refactor the entire thing, write it over in C, make the language cleaner, and I guess that didn't come about. But to his credit, he didn't just talk about it. He generated a working software product with functionality that did not previously exist in Open Source as far as I could tell. His project is worth studying, and I'd encourage works derived from his ideas. I'm sure there's a paper about it online.Bruce

How is that Ironic? I blame Alanis for this total misuse of the word... That's just a coincidence.
While I'm at it, will the people that insist on using the word "literally" to mean metaphorically give it a rest: "That was so funny I literally shit myself" or "That last tackle literally ripped his head off".

You want too see the beauty of Linux Auto detection possibilities boot into knoppix.
I booted of the CD, got fully configured X, working sound, Working Xawtv, Working network with DHCP enabled, and therefore working broadband, and a working CD burner. It took a whole of like one minute to boot and it was everything I neaded. I Actually use it instead of Debian now for my main distro, mounting my old hard drive as scrap space.

Just to add to Bruce's points above: from what I heard, the biggest problem wasn't technical, but rather ESR's refusal to negotiate. The userbase of the kernel config system is the kernel developers; they had several tried-and-true ways of configuring kernels. Many of them were in fact quite happy with the existing system, and didn't see a need to upgrade at all; there was a general consensus that there were some shortcomings in the existing system, but those were very specific.
ESR solved these problems very well with CML2. By he also added a dozen features and changed a hundred other minor things, simply because he felt it was better that way. ESR was solving problems which only he perceived. For example, he was very interested in making it easy for "Aunt Tillie" to configure a kernel. Unfortunately, Aunt Tillie doesn't have a say in whether something goes into the kernel. Linus was apparently OK with CML2, but most of the other kernel developers were very resistant. No one ever explicitly refused CML2, but it never went in either, and ESR eventually gave up.
The impression I got was that ESR should have minimized the changes to the UI in his first version. If he had built something exactly like the old config, but with a new language and backend, most of the objections would have gone away. He then could have submitted the other changes; they may or may not have been accepted, but at least the underlying system would have been improved.
for the curious, you can use dmassage for OpenBSD to get a kernel config file with only your hardware enabled (hardware that was enabled at boot time).
