Is this possible. I did my first one yesterday in order to get my iPod mini to work with the EL kernel. It worked well. Everything went smoothly, but I don't like what I named it. So I'd like to take one more shot at it. If I do, is there a way to remove the old one cleanly? Modules and everything.
Also, if do recompile the kernel again, do I need fresh source, or can I just do a make clean, rename the setting in the Makefile for the name, then go through all the usual steps.
Thanks,
Preston

Sure, it's easy. Just remove the /lib/modules/KERNEL_NAME directory, and then the kernel that you created under /boot. Also remove the initrd in /boot you created (if you created one). You don't HAVE to remove all this though -- it won't cause any problems being there (other than extra crap on your system). You should also remove the kernel entry in /boot/grub/grub.conf.
Also, if do recompile the kernel again, do I need fresh source, or can I just do a make clean, rename the setting in the Makefile for the name, then go through all the usual steps.
You recompile from the same source. Before I compile a fresh kernel I usually do a "make distclean && make mrproper". That will clean up the sources.

If you built RPM package, and installed it that way, rpm -q kernel to see how it is named, than rpm -e kernel-whatever-is-your-version.
If you did make install or something similar to install it, than simply remove the files from the disk (rm -rf). You want to remove /boot/config-version, /boot/initrd-version.img, /boot/System.map-version, /boot/vmlinuz-version and /lib/modules/version. Also, modify your boot loader to reflect the changes (either /boot/grub/grub.conf or /etc/lilo.conf).

Make clean should do it.

Yes ... make clean, change the name in the Makefile, redo what you want and build.
There is no way to remove it automatically (if you didn;t make it as an RPM) ... but it should be fairly easy since all the modules should be in /lib/modules/kernel_name (so after you reboot on your new kernel and it works, remove that /lib/modules directory) ... and everything else you need to remove should be in /boot (the initrd-xxxx.img and vmlinuz- xxxxx).
