Bug Description

grub-initrd-fallback.service should have:

[Unit]
RequiresMountsFor=/boot/grub

If /boot/grub is on a separate filesystem, this can run before that filesystem is mounted and cause problems.

I have run into this with root on zfs. If for some reason the grub directory with grubenv is created on the root pool, then update-grub will no longer work (10_linux_zfs will no longer find valid /boot directories for the root fs).

I would definitely tune this to avoid that as trying to boot into zfs from a grub command line is not a pleasant experience.
