yes. multiboot support went in a few months ago and we can, for
example, load vmware esxi.

I wonder why you would want to chainload grub, however, instead of
using u-root programs that read grub config files and do the boot
directly? There are reasons to use grub, of course, but I was curious
about your specific reason.

thanks
