>Description:
Under some rare circumstances there is a real need to reboot system via kernel's panic from the system console. For example: if any process has ran out of memory nobody can login and even Ctrl-Alt-Del does not work and there is no way to find out source of the problem after cold boot.
And if reboot is not disabled the panic will not decrease the system's security especially; where enabling kernel debugger is not acceptable.

On Sun it is the only way to reboot the working system: OpenBoot prom on boot and reset commands at first checks whether Solaris is running and if it is running - calls its panic routine.
