I also found references to mkinitrd in mkdumprd and the USE_MKINITRD config option, although it is not required by the kdump package. Does kdump need some tweaking too?
yes, the mkdumprd script needs tweaking
kdumptool, on the other hand does not - the string "mkinitrd" and USE_MKINITRD just define which kdump options are applicable for which part kdumptool's job; "initrd" refers to the phase where the kdump initramfs is being build, regardless of which program is used to do so.
