Package: acpi-support
Version: 0.109-5
Severity: normal
Tags: patch
Newer kernels have disabled the /proc interface to power management,
leaving only the /sys. However, the /etc/acpi/power.sh script makes a
decision about running the scripts in battery.d by looking for ac
adapters in /proc (this also affects the running of scripts in ac.d).
The patch below fixes it for me (but this is the first time I have ever
done anything with the /sys power interface, so I don't know how correct
the method for finding ac adapters is).
