Yeah... we talked with Andrew yesterday. He mostly agrees with a black box.
He also said an interesting idea, that if you need compatibility
between the kernels (like we for example, support for migration from 2.6.9 to 2.6.18 in OpenVZ)
you can do image conversion in user-space... Though I think we will prefer simply to have
a compatibility patch for specific kernel versions in our kernel tree (not in mainstream).

Definitely, other ideas/opinions are welcome.
