Hello,
For step2 in early-kdump-howto.txt, --force option of dracut
is necessary to rebuild system initramfs. Without --force option,
executing step2 fails because system initramfs already exists.

Note:
[1]. Early kdump initramfs size will be large because it includes

Hi,
If we remove this, how about explicitly adding a backup process before
rebuilding initramfs for safety's sake? I think there will also be times
when we want to put it back completely.
(It may be good to have such a procedure as well.)
Thanks,
Kazu
[2]. Early kdump inherits the settings of normal kdump, so any changes that
caused normal kdump rebuilding also require rebuilding the system initramfs
