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.
