<title>Description</title>
|
|
|
|
<para>A unit configuration file whose name ends in
|
|
<literal>.slice</literal> encodes information about a slice which
|
|
is a concept for hierarchially managing resources of a group of
|
|
processes. This management is performed by creating a node in the
|
|
control group tree. Units that manage processes (primarilly scope
|
|
and service units) may be assigned to a specific slice. For each
|
|
slice, certain resource limits may the be set that apply to all
|
|
processes of all units contained in that slice. Slices are
|
|
organized hierarchially 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 cgroup settings
|
|
as described in
|
|
<citerefentry><refentrytitle>systemd.cgroup</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.
