I did not see that change.

Did see a slightly smaller kernel size on machine if nvidia card after 
107 dracut. dropped from 180 to 156?

Did find that if I removed the nvidia-gpu-firmware rpm and rebuild 
kernels, they would be about a 100M smaller compared to img files 
on other machines without nvidia hardware?

# rpm -qa | grep nvidia 
nvidia-gpu-firmware-20250808-1.fc42.noarch

In my case, I enlarged /boot to 1.5G so now have enough space.
My Dell Lattitude 5580 has an nvidia card, so those are its kernels.

Have another Dell Lattitude 5580 that doesn't have the nvidia card.

Its kernels are

/boot/initramfs-0-rescue-3b8d97eb0c824e69a66569165466fcc9.img

It doesn't have the nvidia-gpu-firmware file, assume sinde it doesn't 
have the nvidia hardware??

So, seems the dracut creates img files that are about 100M larger if 
nvidia hardware and nvidia-gpu-firmware package installed??
