grub2 support for guests >= karmic

[Loïc Minier]

Hi

For >= karmic guests, grub2 should be installed and used in the guest instead of grub (same logic as for ext4).

cjwatson has a preliminary patch.

Thanks,

[Colin Watson (cjwatson)]

Definitely not ready to go yet though; note e.g. the sh -x in there for testing. I don't have time to work on this further so anyone else should feel free to pick it up given this basis.

So after some tweaks this is apparently almost working, but I get a segfault in grub:

I'm pushing my WIP branch to lp:~lool/vmbuilder/grub2.

(I typoed the --author in the last commit of the branch; will fix this in another branch upload next time)

I'm kind of hesitant accept that branch before this seems to be working. I'm not clued enough to really blame grub2 rather than this integration code. If you can justify that it indeed is grub2, please do so (and open a bug against it).

I do a lot of work in my branch :
lp:~guilhem-fr/vmbuilder/oneiric-support

You can test on recipe.
