OS prober fails when the target OS has a separate boot partition and multiple
initrd images.

I have both Debian and Manjaro installed on my laptop. When using Debian's
update-grub, I get a grub.cfg with a wrong path for Manjaro's initramfs.

It should be:
linux /vmlinuz ...
initrd /intel-ucode.img /initramfs-6.4-x86_64.img

but instead I get:
linux /vmlinuz ...
initrd /intel-ucode.img /boot/initramfs-6.4-x86_64.img


Upon looking at grub.d/30_os-prober.in (line #226), it appears the script only
removes the first occurrence of /boot, so the next image has a wrong path.

(util/grub.d/30_os-prober.in #226)
LINITRD="${LINITRD#/boot}"

Suggestion, something like:

LINITRD="$(echo "$LINITRD" | sed -re 's+(^| )/boot+\1+g')"


Kind regards,
Aeron Draxar
