== Detailed Description ==
As a first pass, the 'inst.sdboot' option already in anaconda should
work. As it stands, that replaces grub+shim with the systemd-boot
loader, and moves the kernel + initrd to the EFI system partition
(ESP).
In general, I think it's great to see this happening. Thank you!
It doesn't attempt to create unified kernel images, so the
existing `dnf update`, `kdumpctl`, and `make install` in a kernel
source directory should all work.
Nitpick: 'make install' invokes /usr/bin/installkernel which (sometimes?)
invokes kernel-install which will create a UKI, if the configuration
specifies that. This sentence implies that 'make install' has some
issue with UKIs, but that is not true.
/usr/bin/installkernel does a lot of stuff, most of it probably wrong.
We could 'ln -sf --relative /usr/bin/kernel-install /usr/sbin/installkernel'
and then 'make install' would work without grubby.
The vast majority of this work has
been done, leaving only two action items, removing grubby from core,
and merging a shimming package (sdubby) into the fedora repos.
As I wrote before in the bug, what is really grubby and sdubby needed for?
Most of what grubby does is arcane archaic stuff that we don't need.
With grubby/sdubby we have an additional layer that adds complexity
and is very inflexible. Why can't we have Anaconda write the Boot Loader
Specification files directly or invoke kernel-install?
