powermgmt-base

common utils for power management

This package contains utilities for power management; beside certain mostly obsolete scripts, you'd want this package for "on_ac_power" which lets you determine whether the system is powered from battery or an abundant supply. It's recommended to use this tool over a simple sysfs check, ConditionACPower or other ad-hoc methods which notoriously fail to account for unobvious quirks, both old and new.

openrc

dependency based service manager (runlevel change mechanism)

OpenRC is a dependency based service manager. It provides support for System V init, for booting, changing runlevels, starting and stopping services, and shutting down. Originally written as a Gentoo project, OpenRC aims at being platform-agnostic. It works equally well on Linux, BSD and Hurd. It supports the traditional init system in Debian in addition to many alternatives. OpenRC is implemented in C in a small, simple and efficient way, making it easy to understand, extend and reuse. This package provides the runlevel change mechanism.

pm-utils

This package provides simple shell command line tools to suspend and hibernate your computer.
