I don't know much about storage and don't really understand what you're
describing (what is a cache device?), but I've been using Checkpoint and
Restore in Userspace (CRIU) [1] to move Linux processes between systems with
different (simulated) hardware. The kernels end up with non-identical state,
but that's fine for my purposes.
