Much simpler than that. Most distributions have a pam module already which updates permissions on things that the "console" user may want to access directly (eg /dev/audio* /dev/cdrom etc) but which should otherwise be protected from misuse (eg people with cronjobs that run eject - an old an very funny SunOS prank)
If your distribution is like most and uses pam_console then see man 5 console.perms and add a rule to the /etc/security/console.perms file for your file. At that point it will happily change the rights back and forth for you as required. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
