Имя (Name)
systemd.slice - Slice unit configuration
Синопсис (Synopsis)
slice.slice
Описание (Description)
A unit configuration file whose name ends in ".slice" encodes
information about a slice unit. A slice unit is a concept for
hierarchically managing resources of a group of processes. This
management is performed by creating a node in the Linux Control
Group (cgroup) tree. Units that manage processes (primarily scope
and service units) may be assigned to a specific slice. For each
slice, certain resource limits may be set that apply to all
processes of all units contained in that slice. Slices are
organized hierarchically in a tree. The name of the slice encodes
the location in the tree. The name consists of a dash-separated
series of names, which describes the path to the slice from the
root slice. The root slice is named -.slice. Example:
foo-bar.slice is a slice that is located within foo.slice, which
in turn is located in the root slice -.slice.
Note that slice units cannot be templated, nor is possible to add
multiple names to a slice unit by creating additional symlinks to
its unit file.
By default, service and scope units are placed in system.slice,
virtual machines and containers registered with
systemd-machined(8) are found in machine.slice, and user sessions
handled by systemd-logind(8) in user.slice. See
systemd.special(7) for more information.
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
slice specific configuration options are configured in the
[Slice] section. Currently, only generic resource control
settings as described in systemd.resource-control(5) are allowed.
See the New Control Group Interfaces
[1] for an introduction on
how to make use of slice units from programs.
Автоматические зависимости (Automatic dependencies)
Implicit Dependencies
The following dependencies are implicitly added:
• Slice units automatically gain dependencies of type After=
and Requires= on their immediate parent slice unit.
Default Dependencies
The following dependencies are added unless
DefaultDependencies=no is set:
• Slice units will automatically have dependencies of type
Conflicts= and Before= on shutdown.target. These ensure that
slice units are removed prior to system shutdown. Only slice
units involved with late system shutdown should disable
DefaultDependencies= option.
