Is there any difference? There are a few ways to open a root shell in Linux using su / sudo. sudo -s (this is my preferred method, it just says "open a shell") sudo su (run su as root - I don't like this, since it's doing the same thing twice, but some people use this) sudo /bin/sh They all rely on sudo to change the UID, and they all depend on having sufficient privileges in the sudoers file for the unprivileged user. You can get more details about the specifics of becoming root on Maemo here: http://wiki.maemo.org/Root_access And some of the history in this older talk thread: http://talk.maemo.org/showthread.php?t=33911 The short version is that gainroot was left as a back-door for developers when the device was put in R&D mode. Installing ssh-server allows you to set a root password at install time, and you can avoid sudo altogether. Installing rootsh provides you with a gainroot that works even when your device isn't in R&D mode - this is likely what your device's previous owner did.
