Hello all, (This is a kind ping for systemd maintainers.)
Before finalising the wording for the release notes, we would like to know if we understood correctly this new network interface naming method. I would like to add a quick note about it in the "installing" chapter, and a full explanation in "whats-new". Below are the questions from last month, and atttached is an updated patch for the release notes. Thanks for your work, and your answers.

+<title>New method for naming network interfaces</title>
+<para>
+The installer and newly installed systems will use a different
+naming scheme for network interfaces instead of <literal>eth0</literal>,
+<literal>eth1</literal> etc.
+The old naming method suffered from enumeration race conditions
+that made it possible for interface names to change unexpectedly
+and is incompatible with mounting the root filesystem read-only.
+The new enumeration method relies on more sources of information,
+to produce a more repeatable outcome. It uses the firmware/BIOS
+provided index numbers and then tries PCI card slot numbers,
+producing names like <literal>ens0</literal> or <literal>enp1s1</literal>
+(ethernet) or <literal>wlp3s0</literal> (wlan).
+USB devices, which can be added to the system at any time,
+will have names based upon their ethernet MAC addresses.
+</para>
+<para>
+This change does not apply to upgrades of jessie systems,
+the naming will continue to be enforced by
+<filename>/etc/udev/rules.d/70-persistent-net.rules</filename>.
+For more information, see
+<filename>/usr/share/doc/udev/README.Debian.gz</filename>
