+          It then spawns /etc/acpi/<ACTION>[/<PARAMETER>] either via run-parts

+          If you must use this, keep in mind it's inherently brittle (for
+          example a mount under chroot won't update it), can't handle modern
+          features like separate per-process filesystem namespaces, requires
+          that your /etc directory be writeable, tends to get easily confused
+          by --bind or --move mounts, won't update if you rename a directory
+          that contains a mount point, and so on. (In brief: avoid.)
+
+          About the only reason to use this is if you've removed /proc from
+          your kernel.
