[PATCH] use dialog (when available) for shutdown/reboot message

[Ronny Standtke <ronny.standtke@fhnw.ch>]

Hi all,

I tested Debian Live with some of my students and they never seem to
notice the final "Please remove ..." message. They are sitting there
staring at the screen waiting for something else to happen. I fixed this
by using a dialog message. The results were much better.

Attached is a patch for live-initramfs.

Greetings

Ronny Standtke
