[Pkg-acpi-devel] Bug#631629: /etc/init.d/acpi-support makes reference to a non-existent /proc file

Package: acpi-support
Version: 0.138-9

Lines 22 and 35 of the current version make reference to
"/proc/acpi/ac_adapter", but no such directory exists. It goes below
some information about the system. It is running on a laptop, so
the effects are noted by the lack of power management capabilities
during the startup.

The absence of the directory may have something to do with kernel
configuration (I'm running the default Debian kernel listed above,
without any changes); according to the file /boot/config-2.6.39-2-amd64,
CONFIG_ACPI_PROCFS{,_POWER} are not set. A proposed workaround is the
substitution of the current test made at the lines pointed above for the
proper evaluation of "on_ac_power", an executable script present in
package powermgmt-base. That package is a dependence of pm-utils, that
by itself is a dependence of acpi-support.
