That's a little like cracking a walnut with a sledge hammer. Let's just
pull the machine out from under the OS and hope it didn't need or want
to do anything prior to shutting down (like oh, I don't know, cleanly
shutting down some RAID and ensuring drive buffers are flushed before a
hard power off?). There's more to a controlled shutdown than a sync and
remount.

Additionally, I can't find a SysRq key on my Mac keyboard. Ancient
legacy "PC" based systems are not the only ones running modern Linux
distributions.
