There's nothing to do with timeout in /etc/grub.d/ anyone but packager
owner and/or upstream should be touching. If you can't control timeout
exclusively via /etc/default/grub and update-grub, then it must be time to ask
grub people via
https://lists.gnu.org/mailman/listinfo/help-grub or report a bug.
