%description
Installation kernel with IPL record for IPL from tape usually for
installation of SLES to LPAR without IPL from CD-ROM or server
available and no z/VM available that can be used do the installation
for LPAR. Only suitable for booting into RAM disks and only used
internally to provide the kernel image with tape IPL record for the
installation CD.
