What is the version parameter in __copy_kernel_and_initramfs used
The version is to handle multiple kernels, eg, PAE vs regular.
I ask because livecd-to-pxeboot looks statically for version 0, if
ever changes it looks like it would cause the script to fail.
There will always be an index of 0 as the "default" kernel.
