Where is the shutdown button on the sheevaplug?

[Bleupomme]

I want to replace my NSLU2 by a sheevaplug I just acquired. I miss the CTRL-ALT-DEL button from the NSLU2, at the moment I am login through ssh to issue a halt command. I there a way to make this work with a button?

The only way I've thought of so far is to add a udev rule that when a certain USB device is connected it runs halt.
easy to configure.  You just need a USB device that you reserve for the process (needs some unique identifier - the iSerial should do).  And a USB port that you keep empty....

That is a good idea indeed. I thought about a mini one key usb keyboard that could send the CTRL-ALT-DEL signal, but did not find one yet. You solution is obviously easier.

Another possibility is to wire a switch(button) to one of the unused GPIOs and use an interrupt from there to initiate a shutdown.  Requires HW and SW changes. (I said it was possible, not easy )

@MarkF, Bleupomme: Shiny Devices provides a single key USB "keyboard" (http://shinydevices.com/products/keystroke-diy) allowing a mix of your approaches.
