Description¶A unit file is a plain text ini-style file that encodes information about a service, a socket, a device, a mount point, an automount point, a swap file or partition, a start-up target, a watched file system path, a timer controlled and supervised by systemd(1), a resource management slice or a group of externally created processes. See systemd.syntax(7) for a general description of the

What is D-Bus? D-Bus is a message bus system, a simple way for applications to talk to one another. In addition to interprocess communication, D-Bus helps coordinate process lifecycle; it makes it simple and reliable to code a "single instance" application or daemon, and to launch applications and daemons on demand when their services are needed. D-Bus supplies both a system daemon (for events suc

OVERVIEW polkit provides an authorization API intended to be used by privileged programs (“MECHANISMS”) offering service to unprivileged programs (“SUBJECTS”) often through some form of inter-process communication mechanism. In this scenario, the mechanism typically treats the subject as untrusted. For every request from a subject, the mechanism needs to determine if the request is authorized or i

Synopsisservice.service, socket.socket, mount.mount, swap.swap Description¶Unit configuration files for services, sockets, mount points, and swap devices share a subset of configuration options which define the execution environment of spawned processes. This man page lists the configuration options shared by these four unit types. See systemd.unit(5) for the common options of all unit configurati

Description¶In systemd, timestamps, time spans, and calendar events are displayed and may be specified in closely related syntaxes. Displaying Time Spans¶Time spans refer to time durations. On display, systemd will present time spans as a space-separated series of time values each suffixed by a time unit. Example: 2h 30minAll specified time values are meant to be added up. The above hence refers t

Namesystemd-resolved.service, systemd-resolved — Network Name Resolution manager Description¶systemd-resolved is a system service that provides network name resolution to local applications. It implements a caching and validating DNS/DNSSEC stub resolver, as well as an LLMNR and MulticastDNS resolver and responder. Local applications may submit network name resolution requests via three interfaces

Running Services After the Network is up So you have configured your service to run after network.target but it still gets run before your network is up?

Description¶A unit configuration file whose name ends in ".service" encodes information about a process controlled and supervised by systemd. This man page lists the configuration options specific to this unit type. See systemd.unit(5) for the common options of all unit configuration files. The common configuration items are configured in the generic [Unit] and [Install] sections. The service spec

Welcome to freedesktop.org freedesktop.org hosts the development of free and open source software, focused on interoperability and shared technology for open-source graphical and desktop systems.

Configuration Directories and Precedence¶The default configuration is set during compilation, so configuration is only needed when it is necessary to deviate from those defaults. The main configuration file is loaded from one of the listed directories in order of priority, only the first file found is used: /etc/systemd/, /run/systemd/, /usr/local/lib/systemd/ [1], /usr/lib/systemd/. The vendor ve

Description¶A daemon is a service process that runs in the background and supervises the system or provides functionality to other processes. Traditionally, daemons are implemented following a scheme originating in SysV Unix. Modern daemons should follow a simpler yet more powerful scheme (here called "new-style" daemons), as implemented by systemd(1). This manual page covers both schemes, and in
