I've added the loop devices to the /dev directory, they should now be 
available as soon as you boot. (in the next version, of course)

I believe you can do this without losetup. To be honest, I haven't 
figured out losetup myself. The last time I tried to use it, I got things 
mounted, then unmounted without a problem. However, when I tried to 
remount them, loop0 was busy. I had to mount on loop1. Each mount and 
unmount forced me to go to the next loop device. 

I normally just mount .img files like:
'mount -o loop filename.img /mnt/cdrom'

If it can be done without losetup, this should be easy. We really don't 
have the room in the boot.img for another application.

I'll see what I can throw together tonight, and post it for testing.

By all means feel free to send me modified scripts.
You can test this yourself for now. Just boot the installer and from VT2, 
you can enter :
mknod /dev/loop0 b 7 0
mknod /dev/loop1 b 7 1
mkdir /mnt/dos
mkdir /mnt/image
mount /dev/hdb1 /mnt/dos
mount -o loop /mnt/dos/disk1.iso /mnt/image

(It may be necessary to use -t iso9660) like:
'mount -o loop -t iso9660 /mnt/dos/disk1.iso /mnt/image'

Let me know how you make out.
