Q: What about custom install and netboot images (and their initrd etc)?, PeterMagnusson
A: Take a look at the Debian Installer instructions for this: http://wiki.debian.org/DebianInstaller/Modify/CustomKernel Although I haven't tried these instructions yet, and they might not quite work with the current Ubuntu Way, they look fairly comprehensive and should at least be a step in the right direction. (MatthewPalmer)
Q: What directory are you in when you run these commands ls -l debian/config/i386/ I'm sure you mean to untar the kernel source you just downloaded and cd into that tree (cd /usr/src ; tar xf linux-source-2.6.17.tar.bz2 ; cd linux-source-2.6.17) but there is no directory debian/config/i386 in there. debian/Config has .config files in it, but no bigiron file so i dono where that kernel comes from? EliCriffield
A: Maybe he meant debian/Config?
A2: On 6.06, the linux-source package does not include the debian directory, it seems. You need to install the source package for linux-image, with a command like
sudo apt-get source linux-image-2.6.15-27-386
Q: Is there any way to get a kernel build faster? I would like to do some "light" kernel hacking. What are the easy steps to just compile a kernel image?
- you can try using make-kpkg, the standard debian kernel-building tool. There are lots of guides around, hopefully the net person to read this page will have more time and put in a link.
Q: What is Ubuntu's default kernel config? The kernel doesn't put anything in /proc/config.
like all debian-based system, ubuntu's kernel puts the config in /boot/config-`uname -r`
Q: Maybe that's not the right place to ask, but I am stuck... I am trying to compile a vanilla kernel (to test an issue with suspend/resume). I do not want to use the make-kpkg method --- too slow on recompiles. So I can compile the kernel, install modules, and then I make the initrd.img with the update-initramfs thing... and all seems to work, but the new kernel simply boots on a BusyBox and does not boot the system. How do I build an initramfs image equivalent to the standard ubuntu one? RomanoGiannetti2
Well, auto-answering. update-initramfs do work. I was bitten by this bug:
http://lists.debian.org/debian-kernel/2006/07/msg00427.html which seems to still exists. Call update-initramfs with -v and it will fail.
Q: What is the correct way to add 'lib/firmware/<custom-kernel>' to a custom kernel .deb so that the kernel and firmware can be distributed together?
Q: Where do the firmware images from the generic kernel come from - (ie which package?) - or how does one get them so one can build a generic kernel? It would be useful if this was explained somewhere.
