Public bug reported:
As per
https://bugs.launchpad.net/ubuntu/+source/makedumpfile/+bug/1564475/comments/19
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.
