Bug#1078656: grub-pc: please use 'grub-install --disk-module=native /dev/sdX'

Package: grub-pc
Version: 2.06-13+deb12u1
Severity: normal
-----BEGIN PGP SIGNED MESSAGE-----

I've been trying to implement a chainloader (see below at /etc/grub.d/40_custom) to boot off external USB disks as needed. Finding external disks requires using GRUB's 'nativedisk', but once that has been executed, the rest of the script cannot be completed because Debian's grub-install enforces BIOS device names (hd0,msdos1) instead of bus names (ata0,msdos1). Further investigating this suggests that if Debian used 'grub-install --disk-module=native /dev/sdX' to install GRUB, this would work as expected.
Alternately, if there's any /etc/default/grub variable I can set to accomplish this, it would suit me just as well.
Thanks!
