After Coiby's patch[1], 92-crashkernel.install will not do anything if grub (zipl for s390) related configuration file doesn't exist. This patch is merged but it is not included in the package released for f35/f36 now. The grubby is required before this patch[2], we changed it to recommend because some fedora variants do not use grubby.

But I think we can add a fallback mechanism that reads the information of the bootloader entries directly from $BOOT/loader/entries/ that is defined by BLS[3].
