1. Redhat Kernel Sources
# rpm -i kernel-source-<version>src.rpm
# cd /usr/src/linux-<version>
# cp /boot/config-<oldversion> ./.config
# <edit> Makefile
Change extra version to the kernel version of your choice. If building on the existing kernel, sue the extra version defined for the distribution. I highly discourage doing this unless you are only compiling new modules into an existing kernel.
# make menuconfig
<selectr your options>
# make dep; make bzImage; make modules; make modules_install
# cp arch/<your arch>/boot/bzImage /boot/vmlinuz-<version>
Modify your boot loader include the new kernel. For EXT3 kernels, you need an extra step described below. RH8/9 {/boot/grub/grub.conf}
2. Kernel.org Sources
Same as above, but the first two steps are replaced with getting the kernel.org sources into that directory (pretty simple)
Making EXT3 support:
cd /boot/
mkdir tmp
cp init-<olderversion>.img init-<version>.gz
gunzip init-<version>.gz
mount -o loop init-<version> tmp
cd tmp/lib/
cp -f /lib/modules/<version>/kernel/fs/ext3/ext3.o .
cp -f /lib/modules/<version>/kernel/fs/jbd/jbd.o .
cd /boot
umount tmp
gzip init-<version>
mv init-<version>.gz init-<version>.img (you can leave this as .gz as long as you change /boot/grub/grub.conf to look for the .gz instead of the .img)

I'm not sure what the document says, but after make bzImage && make modules && make modules_install you can do a "make bzlilo" if you are using lilo as your boot loader and it will copy vmlinuz in /boot or just copy /usr/src/linux/arch/i386/boot/bzImage to /boot and then configure lilo or grub, whatever you have. btw, if you do "make bzlilo" it will work even if you have grub installed instead of lilo ( it will copy the thing to /boot but you will also see a error about lilo.conf, but nothing to worry about ) Alex ----- Original Message ----- From: <carlosh@xxxxxxxxxxx> To: <lartc@xxxxxxxxxxxxxxx> Sent: Tuesday, September 23, 2003 12:09 AM Subject: Official RH kernel documents, and load balancingHi: I have an 'advanced-networking' problem. I want to have two interfaces to the internet, apart from the internal one to the LAN. I came across this page:http://www.redhat.com/mirrors/LDP/HOWTO/Adv-Routing-HOWTO/lartc.rpdb.multiple-links.html and Julian's patches for the kernel published here: http://www.ssi.bg/~ja/ and the How-to: http://www.ssi.bg/~ja/nano.txt So, I downloaded the patch: routes-2.4.22-9.diff (December 14, 2001), and applied it to my 2.4kernel...The kernel re-compile part was fine, following the instructions in : http://tldp.org/HOWTO/Kernel-HOWTO/ The issue is when I have to create a new initrd file.. it appears tocreatea vmlinuz, not a bzImage as the kernel-howto document says. So the new kernel does not boot... Questions: Have anyone done this? I mean, having two connections to the Internet, using RH8.0 or RH 9.0, and having them selecting (balancing) which interface to use to send packets out, and receiving in either seamlessly and with NAT ? I think this functionality should be built in and available, instead of having to patch the kernel? What would you guys recommend? As for the initrd part, any suggestions? Is there an official RedHat "re-build kernel" document?
