+[1]. Early kdump initramfs size will be large because it includes vmlinuz and
 kdump initramfs. And for step 2 if you are sure to overwrite system initramfs
 you can backup the original initramfs and use "--force" option.
 
+[2]. Early kdump inherits the settings of normal kdump, so any changes that
+caused normal kdump rebuilding also require rebuilding the system initramfs
+to make sure that the changes take effect for early kdump. Therefore, after
+the rebuilding of kdump initramfs is completed, provide a prompt message to
+tell the fact.

 After making said changes, reboot your system to take effect. Of course, if you
 want to disable early kdump, you can simply remove "rd.earlykdump" from kernel
 boot parameters in grub, and reboot system like above.
