Thanks, knc1!
I already checked.
On both the pw1 and pw3, there is a "convert" executable in the '/mnt/us/linkss/bin' folder. However this executable is not in the PATH variable.
On the pw3, there is an additional "convert" executable in the '/usr/local/bin' folder - which is in the path variable.
So, that clears up the mystery!
Also, '/usr/local/bin' of the pw3 contains lots of other stuff. These are the goodies you mentioned would be available in the "factory" image, which gets stripped out in the "customer" image, like in my pw1 - which only contains "usbnetwork.sh".
You had also mentioned the possibility of transferring these goodies over to a "customer" image kindle. Would a plain copy work?
Ok. Let me play with 'convert' now..
