If you boot from a RAM disk you still go through a normal boot, with lots of pieces of the system being processed by the Loader to whatever addresses are available when the system asks the memory manager for some memory, etc. That's very different from loaing memory from a snapshot, skipping all that processing that got the stuff there originally. 'course, there would be other problems: you can only load that image on a system with identical hardware, and you need to have a way to get all the hardware back in a state identical to what it was when the snapshot was taken. -- David A.
