In following the thread on bash support in busybox, I've always included the 
full bash on my cd project, since I wasn't clear on a way to check that it 
didn't have any what I guess is bashisms. The script was over 3300 lines 
long, and I was not the original creator of it. I have recently gone thru it, and 
reduced it to about 1900 lines by doing a number of things. I just ran 
checkbashisms on it, found some things it didn't like that were easy to fix.
Use of function, and had one set of ((  )) that should have just been a ( ).

There are two other error types that appear many times in the script.
(unsave echo with backslash) 
echo "\n" 

Don't know how the one would do this without the backslash?

('$(<foo)' should be '$(cat foo)')
specialcommand=$(</tmp/mbr)

This one I could change, actually, it was using cat before, but I found 
something that said this was the better way of doing it.

Hope this is to off topic. 

Again, Thanks for the great work on Busybox...
