I've got a version of Jessie lite that responds to cat /etc/os-release with
PRETTY_NAME="Raspbian GNU/Linux 8 (jessie)"
Trouble is it wouldn't let me apt-get install libopencv-dev or libusb-1.0-0-dev until I overhauled it with
apt-get autoremove && sudo apt-get -f install && sudo apt-get update && sudo apt-get upgrade -y
Thing is the overhauled version still identifies the same as before. Is there some other cmd to pin down different variants of the OS? I'm troubled that sd cards with different behaviours can't be labeled in some way.
