There CentOS goes being annoying...
grub-bhyve loads the grub config file on ubuntu because it is in the
expected place /boot/grub
but because CentOS 6 has a grub 1 config in /boot/grub they put the grub
2 config in /boot/grub2...
note: you can do: source /boot/grub2/grub.conf
or is it 'script' or something
there is some interactive command in grub-bhyve to load a config file
from inside the VM image.
