I've gone ahead and pushed bug# 27705 to master.  That means that there's now a new bootloader "grub-mkrescue-bootloader" in gnu/bootloaders/grub.scm . So you can just override its "configuration-file-generator" by one that doesn't emit the "search" command (remainder should be fine as-is).

I wonder what would happen (to Grub) if someone did guix system reconfigure in a system booted from the ISO9660 image, though.  I think it would be better to not install any bootloader in the case of mkrescue and guix system reconfigure.  We might want to do a follow-up commit that adds a dummy installer to the "installer" field of grub-mkrescue-bootloader.  WDYT?
