NAME
systemd.slice - Slice unit configuration
SYNOPSIS
slice.slice
DESCRIPTION
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.
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
Slice units automatically gain dependencies of type After= and Requires= on their immediate parent slice
unit.
Unless DefaultDependencies=false is used, 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.
