New kernels and corresponding initramf files are created every couple
weeks, and there's a need to seemlessly get the system to boot the
latest. I imagine there are solutions for this that don't involve mods
to EFI vars.

One I imagine is that grub is permanently set to kernel kernel.symlink
with initramfs initramfs.symlink, so that changing kernels is nothing
but changing symlinks. I think hard links would work too.

If that doesn't work in such a low level of boot (and I don't know what
it wouldn't), just name the latest kernel kernel.latest.

As far as poettering's necessary-to-life-itself thing of telling the
EFI what to boot next, I'm pretty sure this could be done a little
farther from the EFI.
