Sorry for being not clearer the first time. How about this?

Subject: [PATCH] fedora: Adjust initrd/kernel paths to real file

In the 32 bit iso:
- isolinux/vmlinuz is a hardlink to images/pxeboot/vmlinux
- isolinux/initrd.img is a hardlink to images/pxeboot/initrd.img

In the 64 bit iso:
- /images/pxeboot/vmlinux is a hardlink to isolinux/vmlinuz
- isolinux/initrd.img is a hardlink to images/pxeboot/initrd.img

This patch adjusts the path so that they point to the real files in
the archive instead of the hardlinks to them.
