Kernel binrpm produces brokes grub2 config

I'm not sure who to blame, but the below commit breaks the kernel binrpm target for me.
It produces a faulty grub2 config.
After installing such a kernel grub2 looks for vmlinuz-XY-rpm and initrd-XY-rpm.
These files are not existing and the machine does no longer boot.
Luckily an addition boot entry without the -rpm suffix exists, if remote access works
one can recover the machine.

My question is, why do we need these copy of vmlinuz anyway?
After calling installkernel on the -rpm variants you delete them again...

This <insert swear word here> happens on openSUSE 13.1, maybe their installkernel script needs fixing.

rpm-pkg: add %post section to create initramfs and grub hooks

/sbin/installkernel is used to insure grub hooks are
inserted and the initramfs is created on the
target system.

The invokation installkernel will work with any
kernel as long as:
- /sbin/installkernel exists
- the kernel and sysem map files are readable
