SYSTEMD.SLICE(5)                                 SYSTEMD.SLICE(5)

     NAME
          systemd.slice - Slice unit configuration

     SYNOPSIS
          slice.slice

     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 m[blue]New Control Group Interfacesm[][1] for an
          introduction on how to make use of slice units from
          programs.

     AUTOMATIC DEPENDENCIES
        Implicit Dependencies
          The following dependencies are implicitly added:

          +o   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:

          +o   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.
