Russell,
Here is the instruction:
http://sourceforge.net/p/xcat/wiki/Using_Provmethod%3Dosimagename/#installing-a-new-kernel-in-the-stateless-image
The files under boot are from the kernel rpm. So please follow the
instruction to make sure that the kernel rpm gets installed in the image.
Thanks,
Ling

Subject: Re: [xcat-user] Building diskless image with different
kernel version
For clarification, this is of course after trying to place the kernels
RPMs and the kernel itself in
"/install/custom/v6.6.0-dl-genesisbuild/kernel" since I tried defining
that path in my osimage definition.

I guess my real question is, what is the correct procedure for building a
stateless image with a different kernel for CentOS 6? I have tried placing
the kernel itself in /install/kernels/$kernel-ver, as well as a repo of
the kernel RPMs and both do not work. Do I need to make the boot directory
itself in the $rootimg_dir and place the kernels there?
Thanks!

Hi Russell,
It looks like it failed at these lines of code in genimage:
# copy the kernel to $destdir
if ( -e "$rootimg_dir/boot/vmlinux-$kernelver") {
cp("$rootimg_dir/boot/vmlinux-$kernelver", "$destdir/kernel");
} elsif ( -e "$rootimg_dir/boot/vmlinuz-$kernelver") {
cp("$rootimg_dir/boot/vmlinuz-$kernelver", "$destdir/kernel");
} elsif ( -e "$rootimg_dir/boot/image-$kernelver") {
cp("$rootimg_dir/boot/image-$kernelver", "$destdir/kernel");
} else {
xdie("couldn't find the kernel file matched $kernelver in
$rootimg_dir/boot");
}
What are the files under
/install/netboot/centos6.6/x86_64/v6.6.0-dl-genesisbuild/rootimage/boot
firectory?
The code is looking for something like
vmlinux-2.6.32-431.el6.x86_64 or
vmlinuz-2.6.32-431.el6.x86_64 or
image-2.6.32-431.el6.x86_64.
Hope it helps,
Ling

Any idea what's bombing here? The errors make no sense.
