Ok, after my major screw-up last week (I directly modified the sudoers file but failed to change the permissions back to 0444), I flashed to the newest OS upgrade and re-installed all of my applications. Now I need to modify the sudoers file and plan to do it CORRECTLY this time, e.g. use visudo. Now my problem - I can't find visudo anywhere on the N800. Is it available separately or am I just not looking in the right place? Or is there some other way that doesn't use visudo? I've looked in /usr/bin and /bin. Thanks much in advance! Nick.
