Re: Compiling a kernel

Hi Patrick,

Hello John,

I always compile my own kernels the Debian (testing) way like this:

-Install the latest Debian linux-source package (currently
linux-source-2.6.17); or you can use vanilla source as you describe
-Make a symlink /usr/src/linux to the resulting
folder /usr/src/linux-source-2.6.17 (is this step still necessary?)

I have wondered this too. I always do it, but it seems like I read
something somwhere suggesting that it is not needed.

-Configure the kernel
-In /usr/src/linux, run "make-kpkg buildpackage kernel-image" (there are other
options, in the man page)
-Install the resulting .deb packages in /usr/src with dpkg -i

Will I still have to configure grub? And will update-grub work or
will I have to manually edit menu.lst? I am still getting the hang of
grub. It was never a part of Slackware and so I had become very
comfortable with lilo.

- Reboot into your new kernel

This will build a kernel without an initrd, so you must compile in all drivers
for the the boot disk(s). Or use the --initrd option.

I prefer to go without initrd myself. Just seems a tad faster, though
probably my imagination.

If you are recompiling a kernel with the same version name, you must
move /lib/modules/[$KERNEL_VERSION] out of the way (you are warned if you
forget!), or you can use the --revision or --append-to-version options to
avoid this.

This is new to me. Will these flags stop clobbering of my modules?
If so, that is a very cool feature. I forget to move my modules at
least half of the time and it really stinks. I think it is because in
Slack since I was going from a 2.4 to a 2.6 it never seemed to
matter. I am going to do some reading on this.

Many thanks for the help.

Patrick
