 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:
