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

[Tadeu Martins]

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.

% lsb_release -a

Distributor ID: Debian
Description: Debian GNU/Linux testing (wheezy)

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.
