Hi thanks for the comment. I am using that script and it gets invoked during the 
build.

Investigating further, I was copying into the wrong output directory.

The way I implemented rootfs updates, is I just have a device directory with the 
skeleton of things I want installed, and it gets copied over the default stuff 
from the build. In the case of the default all I am changing is inittab and 
shadow, but any file could be added there to replace or add to the default 
fs/skeleton.
