If I understand what you are saying, the situation that you describe
seems odd to me.  If I do the command:
           shutdown -p now Power Failure\!
then I expect the machine to power-off if possible, or at least
halt if a power-off is not possible.  Why would I want it to
immediately reboot in that situation?

If I understand your request, you would want
           shutdown -p now
to behave the same as
           shutdown -r now
if the operating system does not know how to power down the hardware.
Is that what you want?

I guess I don't object to that, if that's what you want, but it does
seem a little odd to me.  I assume that an explicit
          shutdown -h -p now
would still halt the machine if the OS doesn't know how to power off
the machine.   By the way, what happens right now if someone does a
          shutdown -r -p now
?  Does that behave the way you want for your situation?
