Yep .... time to learn something new ......


Ahhh.  So "shutdown" sends this request to init by passing an environment
variable to it, either
  INIT_HALT=HALT
or
  INIT_HALT=POWERDOWN

This in the interpreted by some /etc/init.d/ script,
typically /etc/init.d/halt.

So if you want

  shutdown -h now

to always request a power-down, just edit /etc/init.d/halt to always pass
"-p" to "/sbin/halt".
