Not out of the box (you'd need to hack the kernel for that to work I think,
at least on x86) and the devices would need to be _exactly_ identical.
Moreover, if there is read-write mass storage in them, the filesystems on
both would have to be exactly identical as well (including metadata and data
layout etc.).

It may be possible to make it kind of work, but I wouldn't recommend it to
anyone.

Thanks,
