The reason for my question is that after I revert 'screensaver directory symlink hack' which is currently on my kindle and then update to 4.1.0 I won't be able to access system partition (with USBnet) if update for some reason will change the root password.
There is more than one "system partition". Amazon only updates one of them.
If that is not enough reassurance...
You can find links here to v4.1.0 system images and directions on how to install them.
