devd can already do this..
Create a file for /usr/local/etc/devd (doesn't matter what it's called)
with this in it..
notify 10 {
match "system" "ACPI";
action "/usr/local/bin/acpi-ev $system $subsystem $type $notify";
};
The script will be called with "ACPI ACAD _SB_.AC__ 0x00" on power failure=
=20
and "ACPI ACAD _SB_.AC__ 0x01" when connected.
(It is easy to call logger $0 $* in your script to check various events out=
=2E.
=2D-=20
