    Not true.  ls should be able to display the security label.  find should
    be able to locate files that have specific security labels.  cp should
    be able to preserve the security label on copies.  logrotate should be
    able to preserve the security label when rotating logs.  crond should be
    able to check the security label on a crontab spool file to verify
    consistency with the user's credentials with which the cron job will
    run.  login/sshd need to set the security label on the user's terminal
    device.  You'll find plenty of examples of patched userland in SELinux,
    but none of these patches are specific to a particular set of security
    attributes.  They just handle them as strings.
