<para>In the <ulink

<filename>/etc/initrd-release</filename> plays the same role as <filename>os-release</filename> in the
main system. Additionally, the presence of that file means that the system is in the initrd phase.
<filename>/etc/os-release</filename> should be symlinked to <filename>/etc/initrd-release</filename>
(or vice versa), so programs that only look for <filename>/etc/os-release</filename> (as described
above) work correctly. The rest of this document that talks about <filename>os-release</filename>
should be understood to apply to <filename>initrd-release</filename> too.</para>
