This will allow systemd's kernel-install script to generate and install an initrd as per the freedesktop boot loader specs.
See kernel-install(8) for details.
Notice that 'profiles' are not used.
This will eventually be hooked up so that calling "make install" from a kernel build will do the right thing.

Is there a pending patch set you can point me to?

Probably best to commit this as 644. The Makefile takes care of the permissions.

gummiboot does and there are patches for grub (but I don't think they are upstreamed yet), I don't think anyone else do yet. That said, other bootloaders could also add kernel-install hooks of their own to update their configs to point at the correct kernel/initramfs images, so they don't necessarily need to implement the spec to take advantage of this.
I know Sébastien was looking at refind, did you find a simple way to integrate this with refind without it implementing the boot spec?

At least one systemd patch is needed [0], and you need to symlink /bin/installkernel or ~/bin/installkernel to /bin/kernel-install.
I'll resend after addressing your comments.

Sadly, that doesn't work. Refind scan for linux kernel in the efi partition, but if the kernel is not suffixed by .efi, it looks only for files beginning by vmlinuz or bzimage. The boot spec names kernel files linux. I sent a patch[1] proposal to refind forum[2].
I switched all my custom kernel to use kernel-install for 2 months, and I use a custom 90-loaderentry.install[3], which create kernel in the right directory (for grub) and with the right naming (for refind). Letting the directory created by kernel-install empty (two copies are too expensive).
