[Bug 880240] Re: system doesn't turn off if "sudo halt" is given

[Steve Langasek]

Ok, I've worked my way all the way through this bug now, and I have to
conclude this is behavior we can't/shouldn't change.

- The 'shutdown' command has three options: '-h' (halt or power off), '-H' (halt), and '-P' (power off).
- The 'halt' command maps to -H, by design.
- The 'poweroff' command maps to -P, by design.
- The /etc/default/halt configuration *only* affects the behavior when neither -H nor -P has been specified.
- There is no way to make 'halt' by itself map to 'poweroff', without making it impossible to do a real 'halt'.
- These are all standard options that shouldn't be changed.

So I'm closing this bug report as 'wontfix'.  The current behavior is
inconsistent with previous upstart behavior, but that behavior was
buggy.  The current behavior is correct, and I'm afraid people will just
have to learn that 'halt' doesn't mean what you were led to believe it
means.

If you want the system to poweroff, you need to run either 'shutdown -h
now', 'halt -p', or 'poweroff'.  All three commands work.  'halt -p' is
the shortest and probably the most compatible with existing muscle
memory.

Title:
  system doesn't turn off if "sudo halt" is given

Status in “upstart” package in Ubuntu:
  Won't Fix

Bug description:
  Since I upgraded from 11.04 to 11.10 the system doesn't turn off at
  the end of halt procedure if it's called via commandline (local or
  remote shell) . At some point of halt procedure the system freezes and
  all I can do is turning off pc via physical power button and halting
  it using GUI or via "sudo shutdown -h now" , these two methods work
  flawlessly.

   I have this problem on both x86_64 and x86. Anyway if I shut down the
  pc using ligthdm or unity the system is turned off properly.
