This is the first time I release an embedded device based on Linux OS 
(it runs on iMX6ULL CPU).

This device will be produced in a medium scale (100-1000 pieces). I'm 
thinking about root password: should it be the same on all the devices, 
or should it be different?

Each device has a different 4 bytes serial number. I could use it to 
scramble an unencrypted password and obtain an enctrypted password that 
will be the normal root password.

I could disable SSH service at all to be safer, but anyway the board has 
a console over UART that I don't want to disable.

Any suggestions?
