I am trying to boot from an iso that resides on a USB drive (FAT32
formatted), using the following config:

menuentry 'GRML' {
   export iso_path
   loopback loop $iso_path
   set root=(loop)
   configfile /boot/grub/grub.cfg

Selecting the entry causes the machine to reboot.

When I enter the commands on the grub commandline, it reboots at
"set root=(loop)".

Using "configfile (loop)/boot/grub/grub.cfg" correctly shows the
corresponding boot menu but, of course, without changing the root, all paths
referenced in this file won't work.

Did you use bootid at the kernel (linux) line?
This is found at the /conf/bootid.txt on the ISO.
Or you can use "ignore_bootid" instead.
