Thanks for this.

For Xen booting, a combination of load and multiboot is required.  For example, the following line in /boot.cfg works:

menu=Boot Xen:load /netbsd.gz root=dk1 console=pc;multiboot /xen.gz dom0_mem=512M

How can I replace the “root=dk1” part to refer to the root partition by gpt name?

I have tried replacing the “dk1” part with the name of the partition as well as “NAME=name”, but neither works.  I have tried to use the “root” command prior to “load”, but that does not work either.

Is it possible to do this when booting Xen?

Cheers,
