Now granted, your driver is not nearly as complex as sendmail but depending on how it polls CPU/mem usage it may be possible to throw some funky code into a certain register and the driver interprets that as a command and bingo, any user on the system has a neat way of getting root to run scripts. Ok, it's a REALLY long shot. I don't see how your driver could possibly act that way, but it's something to consider when running a daemon. I like the idea of setting up a user (like meter-daemon or something), give it appropriate permissions to /dev/ttyS0, and run the daemon setuid to meter-daemon. -Brian
