+<p>
+Sometimes unplugging and replugging a network device (like a USB WiFi card) can
+rename your net device each time, incrementing the number by one.
+</p>
+
+<p>
+When this happens, you'll see it become <c>wlan0</c>, <c>wlan1</c>,
+<c>wlan2</c>, etc. This is because udev is adding additional rules to its rules
+file, instead of reloading the existing rules. Since udev watches its rules
+directory via inotify, you need inotify support in your kernel config:

+<pre caption="Enabling inotify support in the kernel">
+File systems --->
+ [*] Inotify file change notification support
+ [*] Inotify support for userspace
+</pre>
+
+<p>
+Now udev will retain proper names for your network devices.
