systemd.slice


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.
