I like this idea. Something like rc.conf(5).

Putting the scripts to /libexec would also hide the machine-dependent
ugliness that users should not need to worry about.

Ok.

Again an option in place of "now" sounds indeed fine. Note though that with
acpibat(4) there is a warning-type event before the actual "shutdown" event.

Some x86 systems may indeed do this, mostly during the execution of ACPI
machine code. This also demonstrates the difficulty of choosing the
defaults in the current MD-dominated settings. (But actually, macallan@ and
gsutre@ were working on moving this to wsconsctl(8), but I don't know what
happened to the patches.)
