seems like I'm root running adb shell but when I try to change /system I get busy
rpi3:/ # mount -o remount,rw /system
mount: '/dev/block/mmcblk0p2'->'/system': Device or resource busy
1|rpi3:/ #
Is there something I'm missing?

The '/system' file system contains the Android system of the running OS. You cannot unmount or remount the '/system' file system of a running system. What are you trying achieve?

I've done this on a number androids. For instance, in order to edit 'build.prop' and make a change, you need to remount system as writeable.
mount -o remount, rw /system
allows me to do that.

I am sorry - I stand corrected. Try the following:
mount -o rw,remount /system
