I haven't got the ntfs-3g sorted out yet, but things go better here with than without ntfs-3g.
I think things go wrong in compressing the image and maybe also in using the sparse-file properties without it.
A 'fuse' property of the kernel may be a pre-requisite for all this, and I don't know if that is now
a property of our current kernel or not. Nothing simple here.

It really might be simpler to script all my changes as Werner does than solve all this remastering jazz.
If the remastering capability were a built-in, I have a few uses for it, but nothing huge, anyway.

I cannot figure how to quiet the 'compress isofs' phase, without crashing the process.
Any help there would be appreciated.
