9.12. Strömhantering: Advanced Configuration and Power Interface (ACPI)
The topic of power management is often problematic. Indeed, properly suspending the computer requires that all the computer's device drivers know how to put them to standby, and that they properly reconfigure the devices upon waking. Unfortunately, there are still a few devices unable to sleep well under Linux, because their manufacturers have not provided the required specifications.
Linux supports ACPI (Advanced Configuration and Power Interface) — the most recent standard in power management. The acpid package provides a daemon that looks for power management related events (switching between AC and battery power on a laptop, etc.) and that can execute various commands in response.
Efter denna överblick av grundläggande tjänster som återkommer i många Unixsystem kommer vi att fokusera på miljön för administrerade maskiner; nätverket. Många tjänster krävs för nätverket för att det ska komma igång korrekt. De kommer att diskuteras i nästa kapitel.
