<para>Note that on many SysV systems <command>halt</command> used to be synonymous to
<command>poweroff</command>, i.e. both commands would equally result in powering the machine off. systemd
is more accurate here, and <command>halt</command> results in halting the machine only (leaving power
on), and <command>poweroff</command> is required to actually power it off.</para>
