# from memory (I hope it's correct):

# create file of correct size:
dd if=/dev/zero of=floppy.img bs=1k count=1440

# make a filesystem in the file:
mkfs.msdos floppy.img 
# you can make any filesystem type, i.e.  mke2fs ...

# mount the image as a loopback device:
mkdir -p /mnt/floppyimg
mount floppy.img /mnt/floppyimg -oloop
