    *Sigh*, had you read the LINT kernel config or the man page:
 
 options         SC_DISABLE_REBOOT       # disable reboot key sequence
 
      syscons, sc - the console driver
 
 SYNOPSIS
      options "MAXCONS=N"
      options "SC_DISABLE_REBOOT"
               ^^^^^^^^^^^^^^^^^
 [...]
 
      SC_DISABLE_REBOOT
             This option disables the ``reboot'' key (by default, it is Ctl-
             Alt-Del ), so that the casual user may not accidentally reboot the
             system.
