TBH I'm not clear on whether the executable is -- or more importantly, 
still will be -- needed.

Atm, I'm manually creating the xen.cfg/xen.ini and chainloading via 
GRUB2.  Hence the mess, and asking about simpler approaches.

IIUC, systemd-boot is a rename (fork?) of gummiboot.  WAS going to try 
it awhile ago, as a simpler alternative to Grub2, but saw only that the 
project had been emptied out.  Didn't realize that it'd been subsumed.

Interestingly, from https://en.wikipedia.org/wiki/Gummiboot_(software)

	"Red Hat's Fedora Project does not use gummiboot for booting UEFI 
systems; instead, it will use efilinux to chainload GRUB."

Trying to find out the WHY in the different boot-Xen-on-UEFI approaches, 
let alone simply what just works, is a challenge.
