makekdump should re-exec with cio_ignore on s390x
Status in Release Notes for Ubuntu:
Status in makedumpfile package in Ubuntu:
We should re-exec with cio_ignore lines. As per report there, it
should result in lowered required crashdump setting.
Hypothetically, one should be able to test this imperially by lowering
crashdump memory settings until kdump does not succeed anymore. And
then generated and append `cio_ignore -k -u` to the
KDUMP_CMDLINE_APPEND= and see that kdump starts working again with a
lower memory usage.
Once this is developed / verified / tested, we should probably SRU
this back to xenial.
