reboot after dom0 linux boot up

If I (for example) pass a wrong "root=" option to a dom0-linux kernel,
it panics. so far, mkay a linux way.

Now, different from other panics, there is a counter (of one second!) and
then it reboots. I needed to make it panic three times till I could read
the error message.

Why has that been done this way?

The `restart' option controls this behavior. See any of the xmexample
files for more details.

for/with that ;)

Xen reboots the system on dom0 panic. Stick "noreboot" on the Xen command
line.
