separate /boot partition is not supported in update-grub

While trying to setup a fully encrypted rootfs (with a separate /boot partition), I ended up getting dropped to a grub rescue-shell (see attached shitty pic)
Grub could not find normal.mod
I was able to fix it by changing the prefix variable.
Root cause is that the update-grub script hardcodes the following :
set prefix=(\$root)'/boot/grub'
Which breaks if grub is installed on partition separate from /
I was looking into the same: would it be fine to mount the "efi - uefi" partition (created by asahi installer in 'uefi only' mode) as /boot, and then install grub as grub-install --target=arm64-efi --efi-directory=/boot --removable, and not use the update-grub-script? Later I would also put there the kernel and initram, so that / can be encrypted. (I'm on Void linux btw).
I believe also the update-m1n1 script would need to be changed.
It seems this recent commit b48e491
fixes the issues, so now it should be possible to mount efi partition at /boot without any issues.
This should be fixed in the new scripts, which we'll be releasing soon.
