From the Buildroot documentation at
http://buildroot.org/downloads/buildroot.html :
 target/ which contains almost the complete root filesystem for the
 target: everything needed is present except the device files in /dev/
 (Buildroot can't create them because Buildroot doesn't run as root and
 doesn't want to run as root). Therefore, this directory should not be
 used on your target. Instead, you should use one of the images built in
 the images/ directory. If you need an extracted image of the root
 filesystem for booting over NFS, then use the tarball image generated
 in images/ and extract it as root.
