<para>Note that setting this option to <option>yes</option> or <option>state</option> will only work
correctly with operating systems in the container that can boot up with only
<filename>/usr/</filename> mounted, and are able to automatically populate <filename>/var/</filename>
(and <filename>/etc/</filename> in case of <literal>--volatile=yes</literal>). Specifically, this
means that operating systems that follow the historic split of <filename>/bin/</filename> and
<filename>/lib/</filename> (and related directories) from <filename>/usr/</filename> (i.e. where the
former are not symlinks into the latter) are not supported by <literal>--volatile=yes</literal> as
container payload. The <option>overlay</option> option does not require any particular preparations
