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
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 for an introduction on how to
make use of slice units from programs.
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.
