NAME
systemd.scope - Scope unit configurationSYNOPSIS
scope.scopeDESCRIPTION
Scope 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 --scope may be used to easily launch a command in a new scope unit from the command line.
See the New Control Group Interfaces[1] for an introduction on how to make use of scope units from programs.
AUTOMATIC DEPENDENCIES
Implicit Dependencies
Implicit dependencies may be added as result of resource control parameters as documented in systemd.resource-control(5).Default Dependencies
The 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.
OPTIONS
Scope 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.kill(5) and systemd.resource-control(5). 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.
