only the code.  Since I created the script, I figured I was the right person to 
modify it.  :-) the reason for the change was that lomount as a stand-alone 
program seems to have vanished from the universe and I was frustrated with 
having to load everything up into qemu.  But the sequence in a nutshell was:

Install IP cop in a QEMU session
upload a couple the make/script
restart qemu running IP cop and mount a flash sized disc image.
copy the working system into the flash image, rearrange pieces that wouldn't 
copy and run grub.

Shutdown QEMU and you have your basic working image for flash.  I had a second 
program which would use lomount to mount up the image and install and 
configuration profile for the firewall which would enable it to come up and run 
when installed.

I want to automate the process so that you might do one or two commands and 
you're done.  None of this running the emulator stuff.  I'm doing this in part 
because  if a company has a set of IP cop firewall's, it would be nice to 
automate the flash production process so that they don't have to work hard and 
have a greater chance of getting a properly built/image.

which reminds me, should I be doing a chroot grub to do the install or is it 
okay using the default system grub referring to the grub stage images on the 
target image?

I wonder if part of the problem might be that I have the wrong geometry or 
initial boot sector size.  The other flash seems to be working okay with a 
single sector But I need to check the geometry.
