I don't quite understand what it's supposed to do though. The only thing pygrub
supports is --entry anyway.

I'm suggesting that kernel_internal have things such as:

.bootloader (bootloader path)
.kernel
.ramdisk
.args

For running domains, the last three would be filled in. For created domains,
they would typically be blank, but not necessarily. The way Solaris uses
pygrub, they can be non-blank.
