[syslinux] fixing debian's hd-media image

[Carl Karsten]

I want to eufi boot this image:
http://cdn-fastly.deb.debian.org/debian/dists/testing/main/installer-amd64/current/images/hd-media/boot.img.gz

there is a bug against it:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=913523

I'd like to fix the resulting usb stick for my use, and also fix it in
a way that can be used to fix the upstream bug.

I'm trying to follow the guids
https://www.syslinux.org/wiki/index.php?title=Install#UEFI
and a ml post - here is what I have so far:

https://salsa.debian.org/carlfk-guest/ansible/blob/uefiusb/usbinst/uefi/fix_hdmedia.sh
(likely quite a bit of unneeded copies)

it boots, (good)
Initial menu has no LABEL enries!
boot:
linux boot linux, but no initrd, but i'm sure once I get the .cfg
files worked out that will fall into place.
