For information, the current state of affairs is as follows:
1) pv-grub (legacy) will load grub 0.97 or so config files. It doesn't
understand grub2 configs at all.
2) pygrub understands both grub legacy, and grub2 config files.
3) pv-grub2 will only load grub2 formatted configs.
I am curious as to what people prefer. If you're using a mixed
environment, pygrub is probably the better choice - however there is a
theoretical risk here.
Any migration path to pv-grub2 will require than pv-grub legacy still be
built and distributed - therefore any implementation must be able to be
packaged in parallel with pv-grub legacy.
I would welcome any feedback on this.
