powernap - have the system "take a power nap"; this can be a user
defined program or script at /etc/powernap/action, or the first
supported action among [suspend, hibernate, poweroff]
powernap will run when powernapd(8) has determined that an action needs
to be taken according to its configured parameters.
If the file /etc/powernap/action is executable, then the powernap
binary will run it when called.

* poweroff depending on your hardware’s capabilities, as determined
You may do one of:
1) Write your own custom at /etc/powernap/action and make it
2) Replace /etc/powernap/action with an executable script or binary
3) Symlink /etc/powernap/action to some other executable script or
