Has anyone tried me to create a RAM disk from a file instead of a 
partition?
    To save a partition, it seems possible to make a disk image with
dd and then access it as a device.  However, I am not sure how to 
create a device that would be essentially a dummy, but point to the disk
image.  Any advice?
