Right, so how is this computer even bootable? These kernels, without an initramfs, will face plant on boot.
I've found that anaconda sometimes issues grub2-mkconfig before the initramfs is built, but it got fixed later once new-kernel-pkg called grubby. Yet grubby is failing on this computer, which might be why this entry was never fixed.
The one other time I've seen this behavior, with a missing initrd entry, and grubby's failure to "fix" it, was when I placed /boot on Btrfs (as its own subvolume). This confuses grubby. But I'm not seeing an insmod btrfs in this grub.cfg. And I'm not seeing that this computer has UEFI firmware or it would have an insmod part_gpt.
So I'd like to see the output from:
grub2-install --debug /dev/sda
bash -x grub2-mkconfig -o /boot/grub2/grub.cfg
/boot/grub2/grub.cfg #from the above command
