kernel.spec kernel-install integration

Hi Josh, as mentioned on IRC, here is the patch for the rawhide kernel.spec. This patch is part of an upstream coordination, intended to unify the various ways distributions handle: - installation of kernels in the system - create the matching initrds; hooking up the various implementations of initramfs generators into the kernel package installation process - optionally/automatically create bootable rescue images to be able to recover from failures: https://fedoraproject.org/wiki/Features/DracutHostOnly All the above functionality is provided by the “kernel-install” tool: http://www.freedesktop.org/software/systemd/man/kernel-install.html It features: - flexible hookup/plugin directories to manage kernel installation and uninstallation. initrd, bootloader, rescue image management, all plug into that facility. - strict separation of distribution-supplied logic and local customization logic; system administrators are able to overwrite and replace/extend any part of the default logic if needed - hide distribution-specific logic behind a standardized command line interface - unify the custom kernel installation from the source tree with the usual kernel package installation; like the current /sbin/installkernel
