systemd.scopesystemdsystemd.scope5systemd.scopeScope unit configurationscope.scopeDescriptionScope units are not configured via unit configuration files,
but are only created programmatically using the bus interfaces of
systemd. They are named similar to filenames. A unit whose name
ends in .scope refers to a scope unit. Scopes
units manage a set of system processes. Unlike service units, scope
units manage externally created processes, and do not fork off
processes on its own.The main purpose of scope units is grouping worker processes
of a system service for organization and for managing resources.systemd-run may
be used to easily launch a command in a new scope unit from the
command line.See the New
Control Group Interfaces for an introduction on how to make
use of scope units from programs.Automatic DependenciesImplicit DependenciesImplicit dependencies may be added as result of
resource control parameters as documented in
systemd.resource-control5.Default DependenciesThe following dependencies are added unless
DefaultDependencies=no is set:Scope units will automatically have dependencies of
type Conflicts= and
Before= on
shutdown.target. These ensure
that scope units are removed prior to system
shutdown. Only scope units involved with early boot or
late system shutdown should disable
DefaultDependencies= option.OptionsScope files may include a [Scope]
section, which carries information about the scope and the
units it contains. A number of options that may be used in
this section are shared with other unit types. These options are
documented in
systemd.kill5
and
systemd.resource-control5.
The options specific to the [Scope] section
of scope units are the following:RuntimeMaxSec=Configures a maximum time for the scope to run. If this is used and the scope has been
active for longer than the specified time it is terminated and put into a failure state. Pass
infinity (the default) to configure no runtime limit.See Alsosystemd1,
