• I'm somewhat confused as to how this relates to the assorted ros environment variables: e.g., ROS_ROOT, ROS_PACKAGE_PATH. Do these get put in an approprate setup.bash script that goes in <path>?

• The fact that install-stack always takes a <path> feels like it may be an annoyance. Can <path> somehow be stored in your environment variable so that this isn't necessary? I would expect interaction along the lines of:

  • . ~/myrosinstall/setup.bash
    rosdistro install-stack somestack

• How does the interaction with <local-path> work?

  • Are you responsible for adding <local-path> to the front of ROS_PACKAGE_PATH manually?

  • If you make changes to a stack that something depends on, what is the right way to trigger the appropriate rebuild of everything that depends on it? Should those dependent stacks be installed to <local-path> as well?

  • If you do an upgrade after modifying your ROS_PACKAGE_PATH to include <local-path>, do these upgraded packages get built against the local, or the installed version?

• Why does uninstall-stack talk about an an installation-location? Is this for uninstalling from your main install vs. uninstalling from <local-path>?

• I too am a little worried that there's a lot of <path>s to type. I would like to have it be an "option" which can override an environment variable. And it will complain if neither is set.
