I've been using screen for a while, but recently one of our system administrators noticed an interesting quirk of screen that made me wonder. It seems that if you run 'screen' after running 'sudo bash', the system (as shown by the utilities 'w' and 'who') no longer sees you as "username [priv]", but instead as "root" directly. Is this intentional? It seems as though screen should maintain your identity unless expressly instructed to log you in as someone else. Maybe I'm missing something though?
