+=== Networking in PPCRCD ===
+
+-------------------------------------------------------------------------------
+== Big WARNING as a first thing ==
+    By default sshd server is started, to have easy access if console isn't
+working. But you should disable it, with option </<nosshd>/> if you are in
+unsecure network. Or change root password, after booting it is '<*<ppcrcd>*>'.
+-------------------------------------------------------------------------------
+
+== Bringing up network on boot ==
+    Ultimately <_<udev>_> has complicated things a little, as it detects
+network cards dinamically, but order of interfaces may vary between one and
+annother boot. That's why I support two ways to configure network:
+
+= Old way, disabling udev automation =
+    This way still works, but shouldn't be used anymore.
+    Use new way as I think most problems are solved already.
+
+= New way, dynamic interfaces asignment by udev =
+    If you specify </<eth=>/> option in kernel cmdline or nvram udev when finds
+some interface, checks its driver <*<ethtool -i $IF>*> and uses your
+configuration for it, but this way you can configure only very simple
+connections.
+    For more complicated interface configuration it was normal to save
+<_</etc/sysconfig/interfaces/ifcfg-eth0>_> in configuration. But it depends on
+interface, and we normally can't be sure it will be detected same way next
+time. The only time you can be sure is when you have only one network card,
+but remember, FireWire is detected as network too. To bypass it save your
+configuration to <_</etc/sysconfig/interfaces/</<<module>>/>.ifcfg>_>, without
+specyfying DEVICE. It will be moved by udev script to apropiate ifcfg-</<$IF>/>
+file, and apropiate DEVICE=</<$IF>/> option will be added.
