<para>Unit configuration files for services, sockets,

mount points and swap devices share a subset of

configuration options which define the process killing

parameters of spawned processes.</para>

|
<para>This man page lists the configuration options
|
|
shared by these four unit types. See
|
|
<citerefentry><refentrytitle>systemd.unit</refentrytitle><manvolnum>5</manvolnum></citerefentry>
|
