IBM is signed up to test and provide feedback.
There seem to be a number of work items required to enable this feature: * Add new kernel options using the IPL command and without modifying the content of the parmfile (and run zipl to populate the content). * Temporary overwrite kernel options that are already provided by the parmfile. * Replace the entire boot command line with the VM parameter string; and bypassing any kernel options from the parmfile. * Create new Linux Named Saved Systems (NSS) on the CP/CMS command line. Is the kernel patch IBM is delivering going to do all of these or are there other components affected here?
