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(7) are allowed.
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.
