So BSD systems have this method in their shutdown code called:
die_you_gravy_sucking_pig_dog()
Even Apple’s OS X (derived from BSD) has this in their source, though they change it to:
log_and_exec_reboot_or_halt()
via a #ifdef _APPLE
Further proof that some Apple developers walk around with a stick up their ass (or at least their managers….). This doesn’t apply to all Apple developers, since some of their stuff kicks ass (I’m looking at you Safari)
