I remember this discussion from sime time ago. Debian has changed a real poweroff from "halt" to "halt -p". The second one is according to the manual.
As far as I remeber, "shutdown" is just a wrapper fpr the halt command, but I am not quite sure. But one thing was cleared: To poweroff a debian systenm, the command "halt -p" is recommended. Besides: This behaviour is also now in kali linux integrated, which was also using the command "halt" for a long time. But now it's "halt -p", too, also on the livefile. Best Hans
