Yes, it would be nice to use the Debian Way. But there is not enough
flexibility in their scripts to do what I want.

a) the logic of
     # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
     #GRUB_DISABLE_LINUX_UUID=true
   is odd and, unfortunately, there's no facility for
     GRUB_ENABLE_LINUX_LABEL=true
   (I did have a shot at modifying the scripts, but it's less trivial
   than it would seem at first sight).

b) they insert entries for sysvinit and recovery but not for fsck.
   I modify the first subentry, using the ids fsck and fsck so I can use
   grub-reboot 'fsck>fsck'
   to invoke it from a script that also logs a timestamp. I refuse to
   type monstrosities like
   grub-reboot 'Advanced options for Debian GNU/Linux>gnulinux-advanced-7ccc1c1c-a690-418b-96c0-edcce6ebd3c1'

So it's far easier to write one python script to parse /run/udev/data,
automatically make the changes I want, and keep the original and
edited files as /boot/grub/grub.cfg-{uuids,edited}. After any upgrade,
if the former matches /boot/grub/grub.cfg, it gets overwritten by the
latter.

Cheers,
David.
