It sounds much like a problem I had for several releases. I don't remember how I
solved it exactly, but IIRC, it did start somewhere around F38. My problem was
and
is that all I need, that I'm conscious of, from a Fedora kernel installation, is
to populate /usr/lib/modules/, and populate /boot/ with a kernel and initramfs,
but it stopped doing that much. Eventually I discovered that the grub2-common
package was (still is?) normally required to fulfill that need. I had removed
all
grub*, because I only require one Grub installed per PC, while my installations
average upwards of 20-25 per, and Fedora's isn't the Grub I use.
The fix turned out to be either installing grub2-common, which populates
/usr/lib/kernel/install.d/ with files 20-grub.install and
99-grub-mkconfig.install, or to copy those two files from another installation
that has that package installed, or directly from the rpm, into
/etc/kernel/install.d/. Those two files I've been using for all Fedora
installations through F43 are from F40's rpm version.
It's a dirty fix in that every kernel installation produces several file not
found
errors during kernel installation, but the required population job in /boot/
gets
done, and I don't need to waste space or bandwidth upgrading several unneeded
files or packages.
