The whole point of the verification is to allow safe access to a selected set of raw commands for normal users. root (or rather a process that has CAP_SYS_RAWIO) can send any command. if you need unknown commands just make sure to burn as root, as everything else would be unsafe anyway. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
