Ah, this one. I used fastboot to flash UEFI onto my Hikey 960.

Sort of. By default FAI will not stop if an unknown package is found. You will see a line like this in fai.log:

WARNING: These unknown packages are removed from the installation list:  acroread:i386 flashplugin-nonfree

In FAI install_packages checks every package name and removes unknown
packages. If you want to get an error, you can grep for this error
message and then set the error code. Something like this

if grep -q 'WARNING: These unknown packages are removed' $LOGDIR/fai.log; then
   task_error 777
fi

Also have a look at savelog.LAST.sh.

Yes. We can options to convert the raw image using img2simg or
ext2simg.

Perfect. I will be happy, if can boot my Hikey960 with my own build
image using my own tool :-)
