updates, you also need to have hotplugging enabled in your kernel.
Here's a typical code snippet from the init script:
+[0] mount -t proc proc /proc
[1] mount -t sysfs sysfs /sys
[2] echo /bin/mdev > /proc/sys/kernel/hotplug
[3] mdev -s
+Alternatively, without procfs the above becomes:
+[1] mount -t sysfs sysfs /sys
+[2] sysctl -w kernel.hotplug=/bin/mdev
+[3] mdev -s
Of course, a more "full" setup would entail executing this before the previous
code snippet:
-[4] mount -t tmpfs mdev /dev
