Name

unitfile_slice — Slice unit configuration

Synopsis

name.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 unitfile(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 unitfile_rlimit(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.
