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.

|
type <varname>Conflicts=</varname> and

<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.
