I'm getting ready to do a kernel patch.
I need some good documentation to read first.
Pointers to docs and URLS are welcomed.
(using 10.0)
thnx

Just read up on the 'patch' command.

patch (file you need to patch) (patch file)

Yes, that is in the manual. Examples are good.
Cautions are good too.
Like "don't forget to back up the patched file first".
More cautions anyone?
thanks!

Read /usr/src/linux/README

tis easy, say you're using the -ck patchset.

Untar kernel source (for this case linux-2.6.15.tar.bz2) using command:
Then copy the patch (current one is patch-2.6.15-ck4.bz2) to source folder (linux-2.6.15) and use the following command:
and hey presto your kernel is patched.

Thanks folks. Here's a related question.
I have two partition, RH 9.0 and Slack 10.0. Is there any reason why I can't do the patching by mounting the slack partition, cd'ing to (in my case) /slack/hdb3/usr/src/linux and running patch there..
I note that the diff paths in the patches are relative.

This brings up a related question: Can I compile the slack kernel from the RH partition by modifying the
HOSTCC path in Makefile to /slack/hdb3/usr/bin/gcc?

That will work, just use the absolute path to the patch. e.g. You could do this:
cd /slack/hdb3/usr/src/linux
bzip2 -dc /usr/src/patch-2.6.15-ck4.bz2 | patch -p1

As for the other question, I have never tried that but I know if you want to change the root partition of a kernel you use rdev:
rdev /slack/hdb3/boot/vmlinuz hdb3 #Tell /slack/hdb3/boot/vmlinuz that it's root partition is hdb3

Thanks. Of course the abs path makes sense.
And the reference to rdev was enlightening to say the least.
Never heard of it before, but it's going to be very valuable.
