Since version 198 (Feb 2013) systemd contains kernel-install, a script managing kernel installs. This script allows execution of drop-in scripts for customization. Add such a drop-in script to s390-tools to handle the installation of zfcpdump kernels. It's main purpose is to manage a link to the latest installed zfcpudump kernel at ZFCPDUMP_IMAGE, where zipl expects to find the image to install for a SCSI dumper. The script supports two installation modes. One recommended by the BootLoaderSpecs [1] to /boot/<machine-id>/<kernel-version> directories and one directly to /boot. In the second case files are renamed during installation to <original-name>-<kernel-version> to guarantee unique names. Because the zfcpdump kernel is so special make the script stand-alone and prevent any other script from being executed (exit 77) when a zfcpdump is installed. Especially avoid functionality like creating an initrd (already provided by s390-tools) or creating a boot entry (the zfcpdump kernel should not be used for any other purpose than dumping). The script requires systemd >= 203.
