+          <para>Network interfaces are renamed to give them predictable names when possible (unless

+          device metadata fields. Newer versions of <filename>systemd-udevd.service</filename> take more of
+          these fields into account, improving (and thus possibly changing) the names used for the same
+          devices. With this kernel command line option it is possible to pick a specific version of this
+          algorithm. It expects a naming scheme identifier as argument. Currently the following identifiers
+          are known: <literal>v238</literal>, <literal>v239</literal>, <literal>v240</literal> which each
+          implement the naming scheme that was the default in the indicated systemd version. In addition,
+          <literal>latest</literal> may be used to designate the latest scheme known (to this particular
+          version of <filename>systemd-udevd.service</filename>).</para>
+
+          <para>Note that selecting a specific scheme is not sufficient to fully stabilize interface naming:
+          the naming is generally derived from driver attributes exposed by the kernel. As the kernel is
+          updated, previously missing attributes <filename>systemd-udevd.service</filename> is checking might
+          appear, which affects older name derivation algorithms, too.</para>
