Calling for Smaller Kernel Sources?

FrozedSolid asks: "I can understand that the kernel contains many drivers and support for a lot of platforms, but the fact that the full kernel download can amount to 32mb doesn't make it any easier to download with a 56k modem. Kernel patches are nice, but obviously only apply when you have access to an entire kernel tree beforehand. Is there a way you can download a leaner linux kernel source? Is there a place that carries sources for x86 only or possibly sources without some of the less popular drivers?"

Actually,

32MB is not too much to ask. On 56k, that amounts to like a few hours of download. Let's assume 5K/s (I used to get 2 in Windows, but 7 is Linux for some reason). That's 300K/min. That's 1 MB every 3.5 minutes. That's 32MB in ~120 minutes, or 2 hours.

If you haven't gotten cable, and you're using Linux, the distros themselves are at a magnitude greater in size; I doubt that kernel sources are the real problem.

RSYNC!!!

You need rsync.

It was devised to combat just the problem you cite.

rsync://rsync.kernel.org/pub/[wherever you want to go]

Thank you, TRIDGE!

Seek bandwidth elsewhere.

Never under-estimate the bandwidth of a plane full of CD's... ...or the CD-RW drive at your nearest Internet Cafe.

Hey, this does sound interesting. I have a few spare computers around and a little knowledge of PERL... I think that I'll look into this tomorrow. That would be _really_ neat. If I do manage to get something working, I (of course) will insure that it won't remain that way for long by posting it back up here...

It really shouldn't be too hard. I've been staring at your post thinking for a bit, and the best way to do it that I can think of is to read in the config template file from the kernel source tree (have several selectable versions) and generate a huge page full of radio-select buttons. Once that is submitted, an MD5 hash is applied to the generated config file. If it matches an existing package (unlikely at best), simply serve that up. Otherwise, make a new build tree named "builds/$VERSION/$MDSUM" and copy the config file into it. Build the kernel, tar.gz the resulting modules and kernel image, and email the links to the person.

This would require quite a bit of CPU horsepower, but it would make for a nice, small kernel download and a sort of set-and-forget build. Set the options and press the button on your lunch break, and have the link sitting in your inbox when you get home (unless it's slashdotted, in which case I'll come home to a hole melted in my floor where a server and accompanying cable modem used to be).
