Windows 8 and Some common directives that you will find in the [Unit] section are:.

Using these directives and a handful of others, general information about the unit and its relationship to other units and the operating system can be established. On the opposite side of unit file, the last section is often the [Install] section. This section is optional and is used to define the behavior or a unit if it is enabled or disabled. Enabling a unit marks it to be automatically started at boot. In essence, this is accomplished by latching the unit in question onto another unit that is somewhere in the line of units to be started at boot.

Because of this, only units that can be enabled will have this section. The directives within dictate what should happen when the unit is enabled:.

Sandwiched between the previous two sections, you will likely find unit type-specific sections. Most unit types offer directives that only apply to their specific type. These are available within sections named after their type. We will cover those briefly here. The device , target , snapshot , and scope unit types have no unit-specific directives, and thus have no associated sections for their type.

The [Service] section is used to provide configuration that is only applicable for services. This categorizes services by their process and daemonizing behavior. This is important because it tells systemd how to correctly manage the servie and find out its state.

The directives to do this are:. Socket units are very common in systemd configurations because many services implement socket-based activation to provide better parallelization and flexibility.

Each socket unit must have a matching service unit that will be activated when the socket receives activity. By breaking socket control outside of the service itself, sockets can be initialized early and the associated services can often be started in parallel. By default, the socket name will attempt to start the service of the same name upon receiving a connection. When the service is initialized, the socket will be passed to it, allowing it to begin processing any buffered requests.

Mount units allow for mount point management from within systemd. Mount points are named after the directory that they control, with a translation algorithm applied. The result of this translation is used as the mount unit name. Mount units will have an implicit dependency on other mounts above it in the hierarchy. For the unit definitions automatically created and those that you wish to define in a unit file, the following directives are useful:.

This unit allows an associated. As with the. The [Automount] section is pretty simple, with only the following two options allowed:. Swap units are used to configure swap space on the system.

The units must be named after the swap file or the swap device, using the same filesystem translation that was discussed above. The [Swap] section of a unit file can contain the following directives for configuration:. A path unit defines a filesystem path that systmed can monitor for changes. Another unit must exist that will be be activated when certain activity is detected at the path location.

Path activity is determined thorugh inotify events. Timer units are used to schedule tasks to operate at a specific time or after a certain delay. This unit type replaces or supplements some of the functionality of the cron and at daemons. An associated unit must be provided which will be activated when the timer is reached. The [Slice] section of a unit file actually does not have any. Instead, it can contain some resource management directives that are actually available to a number of the units listed above.

Some common directives in the [Slice] section, which may also be used in other units can be found in the systemd. These are valid in the following unit-specific sections:.

We mentioned earlier in this guide the idea of template unit files being used to create multiple instances of units. In this section, we can go over this concept in more detail. Template unit files are, in most ways, no different than regular unit files. However, these provide flexibility in configuring units by allowing certain parts of the file to utilize dynamic information that will be available at runtime. Template unit files can be identified because they contain an symbol after the base unit name and before the unit type suffix.

A template unit file name may look like this:. When an instance is created from a template, an instance identifier is placed between the symbol and the period signifying the start of the unit type.

For example, the above template unit file could be used to create an instance unit that looks like this:. An instance file is usually created as a symbolic link to the template file, with the link name including the instance identifier. In this way, multiple links with unique identifiers can point back to a single template file. When managing an instance unit, systemd will look for a file with the exact instance name you specify on the command line to use.

If it cannot find one, it will look for an associated template file. The power of template unit files is mainly seen through its ability to dynamically substitute appropriate information within the unit definition according to the operating environment.

This is done by setting the directives in the template file as normal, but replacing certain values or parts of values with variable specifiers. The following are some of the more common specifiers will be replaced when an instance unit is interpreted with the relevant information:. By using the above identifiers in a template file, systemd will fill in the correct values when interpreting the template to create an instance unit. When working with systemd , understanding units and unit files can make administration simple.

Unlike many other init systems, you do not have to know a scripting language to interpret the init files used to boot services or the system.

The unit files use a fairly simple declarative syntax that allows you to see at a glance the purpose and effects of a unit upon activation. Breaking functionality such as activation logic into separate units not only allows the internal systemd processes to optimize parallel initialization, it also keeps the configuration rather simple and allows you to modify and restart some units without tearing down and rebuilding their associated connections.

Leveraging these abilities can give you more flexibility and power during administration. What do Systemd Units Give You? Where are Systemd Unit Files Found? Where would you like to share this to?
