I have tried this. After running update-devfsd or reboot, /dev/tts/0 ends up as root.nut 0660. However, the symlink /dev/ttyS0 is still root.root 0555. Is there something else that needs to be done to files in /etc/devfs to make /dev/ttyS0 owned by root.nut with mode 0660? > > Just alter to suit your needs.
