Hi, In 9990-networking.sh (git HEAD) there is the following code (the same code snippet is available in 3.0~a24-1ubuntu1, the version available in Ubuntu Precise):

Imho you should be able to use BOOTIF to specify the device to boot from even if any of them are set. They have nothing to do with eachoterh. I.e 'if [-n "$BOOTIF}" ] ... fi' should be move before the 'if [ -s "${NFSBOOT}" ...".
