It's a udev rule. Mine looks like this, tweak yours $ grep -r uucp /lib/udev/rules.d/ /lib/udev/rules.d/50-udev-default.rules:KERNEL=="tty[A-Z]*[0-9]|pppox[0-9]*|ircomm[0-9]*|noz[0-9]*|rfcomm[0-9]*", GROUP="uucp" You'd put your file in /etc/udev/rules.d/, not in /lib/ as above, that's the as-shipped location for defaults -- Alan McKinnon [email protected]
