Add parsing of dracut cmdline option "rd.dasd=..." at initrd runtime. It delegates configuration to chzdev. Implement `dracut --print-cmdline` and `dracut --hostonly-cmdline` for initrd build time. Emit an rd.dasd option for each DASD disk in dracut's device dependency graph (to mount the root-fs, or to access the kdump target). This allows a distribution independent device configuration. Configuration is consistent by using chzdev as backend. It also prevents duplicate activations of the same device. Copy the udev rule for unique DASD device nodes under /dev/disk/ [59-dasd.rules] into initrd for the same functionality like 95dasd or 95dasd_rules. Along with the existing functionality of zdev/dracut, it makes the following dracut modules superfluous: https://github.com/dracutdevs/dracut/tree/master/modules.d/95dasd https://github.com/dracutdevs/dracut/tree/master/modules.d/95dasd_mod https://github.com/dracutdevs/dracut/tree/master/modules.d/95dasd_rules Github-ID: https://github.com/ibm-s390-linux/s390-tools/pull/158 Acked-by: Vineeth Vijayan <vneethv@linux.ibm.com> Acked-by: Peter Oberparleiter <oberpar@linux.ibm.com> Signed-off-by: Steffen Maier <maier@linux.ibm.com> Signed-off-by: Jan Höppner <hoeppner@linux.ibm.com>
