Kinetic install not setting ROS_ environment variables
I've followed the instructions to install Kinetic on Ubuntu 16.04, and there were no errors during the install, but the setup scripts aren't setting up the ROS_ environment variables. (ROS_ROOT, ROS_PACKAGE_PATH). My setup scripts are in /opt/ros/kinetic. setup.bash just runs setup.sh, but looking at setup.sh, it doesn't seem to be setting or exporting any ROS_ variables. There are no errors generated, including nothing about problems with the temp file. It also looks like it runs _setup_util.py, but I see no mention of any ROS_ environment variables in that file either. The CATKIN_ variables aren't getting set either, but I have catkin installed. I haven't set up any workspaces yet, since I'm trying to get the install right.
It seems like the environment isn't right, but looking at the scripts I don't see any place where the ROS_ variables should be set, so I'm wondering if the docs might be out of sync with Kinetic. If the docs are correct, could anyone point me in the right direction to fix this?
