As of v220, systemd provides systemd-boot (formerly gummiboot)

     https://wiki.archlinux.org/index.php/Boot_loaders#systemd-boot
     https://wiki.archlinux.org/index.php/Systemd-boot#EFI_boot

and is apparently capable of booting EFISTUB kernels.

Will the aforementioned goals enable direct boot using systemd-boot on 
EFI platforms ?  Or is it possible even now?

As my current test distro is Opensuse, with systemd v < 220, I've not 
yet tested.
