It depends on your user space setup.

I'm using busybox with init enabled together with the following line
in my /etc/inittab:

::sysinit:/etc/init.d/rcS

The file /etc/init.d/rcS looks like this:
#!/bin/sh

# sysfs is mandatory
mount -t sysfs none /sys

# optional filesystem support
mount -t proc none /proc
mount -t tmpfs none /tmp

# use tmpfs for /dev
mount -t tmpfs -o sizedk,mode\a55 tmpfs /dev

# optional /dev/pts filesystem support
mkdir -p /dev/pts
mount -t devpts none /dev/pts

# setup mdev as hotplug handler
if [ -f /proc/sys/kernel/hotplug ]; then
  echo /sbin/mdev > /proc/sys/kernel/hotplug
else
  /sbin/sysctl -w kernel.hotplug=/sbin/mdev
fi

# udev replacement
mdev -s

# setup local network interface
ifconfig lo 127.0.0.1 up
