I'm getting my feet wet with kernel hacking. I've got a couple of build trees on my system now (2.6.32.21 & 2.6.35.4); but neither matches the one I'm running (2.6.32-24). I can't find that one anywhere. My question, then: How do I install a kernel from source as the kernel to use with the system I am currently running so that I can insert and run modules I build against my tree? I would appreciate tips and links, too. | |||

I've been doing minor kernel work since the 1.2 days, so it's just possible I'm behind the times. I'm sure others will chime in if I'm off base :) For this kind of thing, Grub is your friend (assuming you're using Grub. If not, LILO can do most of this too). Your current kernel is a great home-base, keep that, don't touch it. To make a kernel from source is actually a pretty well documented method. Once you've done the final If it doesn't work, perhaps there were interesting error messages when you booted. Boot back to your stock kernel and rebuild the bits you need. Install. Wash, rinse, repeat until you've booted. Hooray! You're now running a stock kernel. Assuming you really are kernel hacking, I'm assuming you're just tweaking modules or perhaps making new. In that case, you need to be very aware of That tells it to just make the modules in that directory. That way you don't have to rebuild the entire thing. If you've booted into that kernel, you can safely copy out the old modules from /lib/modules and copy in the new ones, rmmod, insmod, and load the new module (assuming you can). You can wash, rinse, repeat with this method many times. Hopefully this gets you on the path you're looking for. | |||
