This is a test vm, so no worries about not being bootable. I am using
pygrub and Xen. I looked in the 40_custom and it didn't look like the

will have to check later.

make it so simple that there are obviously no deficiencies. And the other
way is to make it so complicated that there are no obvious deficiencies."
