<listitem><para>Takes one or more arguments, separated by whitespace, each declaring a symlink to
create within the new file system. Each argument is a pair of symlink source and target paths,
separated by a colon. This option may be used more than once to create multiple symlinks. When
<varname>CopyFiles=</varname> and <varname>MakeSymlinks=</varname> are used together the former is
applied first.</para>
<para>The primary use case for this option is to create symlinks that need to exist before
<citerefentry><refentrytitle>systemd-tmpfiles</refentrytitle><manvolnum>8</manvolnum></citerefentry>
is executed. For example, when using
<citerefentry><refentrytitle>systemd-confext</refentrytitle><manvolnum>8</manvolnum></citerefentry>,
this setting can be used to create symlinks in <filename>/var/lib/extensions.mutable</filename> to
redirect writes to mutable confexts to a custom location.</para>
<para>Consider using
<citerefentry><refentrytitle>systemd-tmpfiles</refentrytitle><manvolnum>8</manvolnum></citerefentry>
with its <option>--image=</option> option to pre-create other symlinks (as well as other inodes) with
fine-grained control of ownership, access modes and other file attributes.</para>
