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. http://www.criu.org/Main_Page Christopher -- Employee of Qualcomm Innovation Center, Inc.
