[redhat] kernel.spec: increase initramfs reservation from 20MB to 40MB
When packaging the kernel we create a dummy 20MB file in the rpm build
root so that installation requires at least this much free space in
/boot. Unfortunately, we still get reports of boot failures due to
dracut having failed to write the postinstall generated initramfs to
/boot.
We did a simple analysis of the systems we have access to and found the
average initramfs size to be a little over 30MB. So let's double the
reservation file size to 40MB. That should protect more uses and
hopefully will not create a burden on others.
