SYSTEMD.SLICE(5)                systemd.slice               SYSTEMD.SLICE(5)

NAME         top

       systemd.slice - Slice unit configuration

SYNOPSIS         top

       slice.slice

DESCRIPTION         top

       A unit configuration file whose name ends in ".slice" encodes
       information about a slice which 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 it.

       By default, service and scope units are placed in system.slice,
       virtual machines and containers registered with systemd-machined(1)
       are found in machine.slice, and user sessions handled by
       systemd-logind(1) in user.slice. See systemd.special(5) 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.

AUTOMATIC DEPENDENCIES         top

       Slice units automatically gain dependencies of type After= and
       Requires= on their immediate parent slice unit.

       Unless DefaultDependencies=false is used in the "[Unit]" section,
       slice units will implicitly 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 early boot
       or late system shutdown should disable this option.
