The name switch is announced via a warning message when you emerge udev:

WARN: postinst

udev-249 defaults to predictable interface renaming, as described in
the URL below:
https://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames

If you wish to disable this, please see the above documentation, or set
net.ifnames=0 on the kernel command line.

You can change settings for log messages in make.conf, see
/usr/share/portage/config/make.conf.example for documentation (search
for PORTAGE_ELOG). I have
PORTAGE_ELOG_SYSTEM="save echo:error,warn,log" in my make.conf. echo
means the messages are displayed again when emerge exits.
