12 A unit configuration file whose name ends in ".slice" encodes
13 information about a slice which is a concept for hierarchically
14 managing resources of a group of processes. This management is
15 performed by creating a node in the Linux Control Group (cgroup) tree.
16 Units that manage processes (primarily scope and service units) may be
17 assigned to a specific slice. For each slice, certain resource limits
18 may be set that apply to all processes of all units contained in that
19 slice. Slices are organized hierarchically in a tree. The name of the
20 slice encodes the location in the tree. The name consists of a
21 dash-separated series of names, which describes the path to the slice
22 from the root slice. The root slice is named, -.slice. Example:
23 foo-bar.slice is a slice that is located within foo.slice, which in
24 turn is located in the root slice -.slice.
25
26 By default, service and scope units are placed in system.slice, virtual
27 machines and containers registered with systemd-machined(1) are found
28 in machine.slice, and user sessions handled by systemd-logind(1) in
29 user.slice. See systemd.special(5) for more information.

31 See systemd.unit(5) for the common options of all unit configuration
32 files. The common configuration items are configured in the generic
33 [Unit] and [Install] sections. The slice specific configuration options
34 are configured in the [Slice] section. Currently, only generic resource
35 control settings as described in systemd.resource-control(7) are
36 allowed.

38 Unless DefaultDependencies=false is used, slice units will implicitly
39 have dependencies of type Conflicts= and Before= on shutdown.target.
40 These ensure that slice units are removed prior to system shutdown.
41 Only slice units involved with early boot or late system shutdown
42 should disable this option.
