beaglebone-black-make-microSD-flasher-from-eMMC.sh Will not work with 4.1.x kernels #79

This may help others that are debugging this issue.

As mentioned in this thread https://groups.google.com/forum/#!category-topic/beaglebone/AGuWaV4sdKo

When you use the updated boot-scripts : beaglebone-black-make-microSD-flasher-from-eMMC.sh to create a 'clone' of your 4.1.x system it does not boot into the root filesystem properly.

Why would you use kernel 4.1.x instead of 4.4.x ? Because it came installed in my industrial beaglebone.

@rmilne or you know what is better!! Someone on v4.1.x who fixes it..

Here's the generic check we use for 3.8.x, (and thus assume uuid) at 4 places. Feel free to extend this check to also check for 4.1.x based kernel..

if [ -d /sys/devices/bone_capemgr.*/ ] ; then

Here are the 4 places a patch would be required..
