In that case there's already some logic available in powerd(8). It's
trivial to make it exit(2) in situations where it doesn't find a power
That's a bit different from the current code where it checks first that
/etc/powerd/scripts/<power_type> is present, then falls back to
Exposing the power management backend as a read-only sysctl is also an
IMHO, powerd(8) shall exit unless there is code that explicitly
registers a backend. It has no real meaning (to me, at least) to handle
power events where there is nothing expecting it to be so.
There, /etc/powerd/scripts would rather be:
Or even move away "scripts" entirely. Nothing specifies that these
