But if I push the power button, the init process
doesn't seem do change the runlevel, and power off
immediatly.
I can see the message "Shutdown requested..." and then
- power off -.
I think this souldn't be so.
Also I think it is a bit dangerous if everyone can
switch of the system, clean or unclean, just by
pushing the button.
Maybe a 5 second push-time would be good (like ATX)
but with a gracefull shutdown.
After all the halt script does not power off my
715/80.
I have to switch it off manually.
