grub does exactly what grub.cfg tells it to do. And grub.cfg searches
for /root part of the host used to install grub. I'm not sure why you
thing it "should" do something different.

If everything you want is to display single menu entry, you do not need
grub-mkconfig at all. Just create grub.cfg that contains this single
menu entry in your boot directory.
