RE: install script for fwupdate
Ard,
"fwupdate" was replaced by "fwupd". At least in Debian it's a transitional package now, and will guide you towards fwupd.
In fwupd it uses /sys/firmware/efi/efivars though already.
So I'd say it's not worth your effort filing anything on this transitional package stuff.
Thanks,
