halt(8):
-p When halting the system, do a poweroff. This is the
default when halt is called as poweroff.
reboot(2):
LINUX_REBOOT_CMD_HALT
(RB_HALT_SYSTEM, 0xcdef0123; since 1.1.76). The message `System
halted.' is printed, and the system is halted. Control is given
to the ROM monitor, if there is one. If not preceded by a sync(2),
data will be lost.
LINUX_REBOOT_CMD_POWER_OFF
(0x4321fedc; since 2.1.30). The message `Power down.' is printed,
the system is stopped, and all power is removed from the system,
if possible. If not preceded by a sync(2), data will be lost.
