I've been messing around with Flash RAM reading and writing, and I
fell short of being able to produce a disk image indirectly.  To be
more explicit, I tried to create a virtual disk in a conventional file
(/tmp/flash) using the /bin/disk/ utilities, but they seem to fall
short of my objectives, in that they need to write the /dev/sd??/ctl
file which is not available to a virtual disk.  Has anyone considered
writing a fileserver that simulates /dev/sd??  in a file image?  Have
I simply overlooked the obvious?

If it's not been done yet, is it going to be difficult and will anyone
else find it useful?

PS: Is anyone familiar with Flash RAM to the extent that they can
explain why one does not seem to be able to access the entire storage,
for example, using dd?  Or point me to some useful documentation?
