because the .img file refers to the .dat file, it's not quite that
simple.  you need to edit the .img file and replace the first line
with a line that matches the 8.3 dos filename of the .img file.
i.e., you need to replace:
    data:  debxo-awesome.jffs2.dat
with something similar to:
    data:  debxo-~1.dat

it might be better to give the images 8.3 names in the first place,
but i'll understand if you resist.  :-)
