-
- <para>A unit configuration file whose name ends in
- <literal>.slice</literal> 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,
- <filename>-.slice</filename>. Example:
- <filename>foo-bar.slice</filename> is a slice that is located
- within <filename>foo.slice</filename>, which in turn is located in
- the root slice <filename>-.slice</filename>.
- </para>
-
- <para>By default, service and scope units are placed in
- <filename>system.slice</filename>, virtual machines and containers
- registered with
- <citerefentry><refentrytitle>systemd-machined</refentrytitle><manvolnum>1</manvolnum></citerefentry>
- are found in <filename>machine.slice</filename>, and user sessions
- handled by
- <citerefentry><refentrytitle>systemd-logind</refentrytitle><manvolnum>1</manvolnum></citerefentry>
- in <filename>user.slice</filename>. See
- <citerefentry><refentrytitle>systemd.special</refentrytitle><manvolnum>5</manvolnum></citerefentry>
- for more information.</para>
-
- <para>See
- <citerefentry><refentrytitle>systemd.unit</refentrytitle><manvolnum>5</manvolnum></citerefentry>
- 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
- <citerefentry><refentrytitle>systemd.resource-control</refentrytitle><manvolnum>7</manvolnum></citerefentry> are allowed.
- </para>
-
- <para>Unless <varname>DefaultDependencies=false</varname>
- is used, slice units will implicitly have dependencies of
- type <varname>Conflicts=</varname> and
- <varname>Before=</varname> on
- <filename>shutdown.target</filename>. 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.
