Maybe grub_prefix should be setable on the command line of grub-install?
Or some other bad mistake on my part because of scoping the amount of

It should be never needed to change grub-install to fix this.
If /boot is a seperate partition then the prefix gets just /grub.
If not then it's a bug. And in that case the generated grub.cfg has the
same problem.
This is actually impossible that only grub-install but not grub-mkconfig
was affected in your case. They use both the same function to make it
relative to the root.
Did you run grub-install again after you mounted your /boot or did you
just copy the files?
