[sclug] Disable 'Ctrl-Alt-Del' reboots

[Neil Owens]

I've finally had the spare minute to find out how to prevent the 3 fingered
salute from rebooting my IPCop firewall (I think) - /etc/shutdown.allow

Is this normally installed on Linux boxes? - I'd have thought that any
'server' based machine would have it on, as opposed to the default of having
it off - so to speak ;-)

But I'm new to all of this so thought I'd ask the experts.
