hey all -

i've been reading the mount_* manpages recently, wondering if 
NetBSD can mount the contents of a binary disk image into the 
global filesystem namespace.   i haven't found anything 
conclusive, so i thought i'd ask.

the idea is simple.. if i make a binary disk image of a floppy or CD:

     dd if=/dev/fd0a of=disk.img

i'd like to mount that image as a file tree:

	mount_image disk.img /mnt

without having to write it back to a block-special device, first.

given what mount_null, mount_union, mount_overlay, and mount_mfs 
can do, it doesn't seem too outrageous to think that we could 
read and write a binary image as if it were a device.
