<para>prevent pluto from restarting after it crashed. This option should
only be used by developers when debugging a crasher. It will prevent
overwriting a core file on a new start, or a cascade of core files. This
option is also required if used with plutostderrlog= to avoid clearing
the logs of the crasher. Values can be yes (the default) or no.

<para>
This option is ignored on modern init systems such as 
<citerefentry><refentrytitle>systemd</refentrytitle><manvolnum>1</manvolnum></citerefentry> and upstart. For
systemd, change the  <emphasis remap='I'>ipsec.service</emphasis> file to contain <emphasis remap='I'>Restart=no</emphasis>. See
<citerefentry><refentrytitle>systemd.service</refentrytitle><manvolnum>5</manvolnum></citerefentry>
