[clue-tech] re: Disabling shutdown.

[David Rudder]

I have needed to prevent an inquisitive 3 year old from shutting down my 
servers. He likes hitting buttons. Actually, I like him hitting 
buttons...just not the power button on my server :)

I /etc/acpi/actions/power.sh. It disabled the easy push-to-restart. You 
can still do a hard power-off by holding the button for 5 seconds, but 
it prevents accidental restarts. I don't have the file on me, but if 
you'd like I can send it to you tonight, if you'd like.

I don't know if any software systems (KDE, gnome, etc) use the ACPI 
infrastructure for shutting down.
