According to its readme file:

  - Very early in the boot process, the /dev directory should get a 'tmpfs'
    filesystem mounted, which is populated from scratch by udev. Created nodes
    or changed permissions will not survive a reboot, which is intentional.

  - The content of /lib/udev/devices directory which contains the nodes,
    symlinks and directories, which are always expected to be in /dev, should
    be copied over to the tmpfs mounted /dev, to provide the required nodes
    to initialize udev and continue booting.

We're not using /lib/udev/devices, as you can see in our udev task.
Instead, we simply invoke mknod for each one of these expected
devices.
