ROS stack setup script outputs to non-standard path

Question

Hi,

I noticed that in the current script, the full ROS stack is being built into into:

/opt/ros/$ROS_DISTRO/install/setup.bash

rather than the default:

/opt/ros/$ROS_DISTRO/setup.bash

This feels a bit non-standard and could cause confusion or compatibility issues with existing tools and environments that expect the default setup.bash path.

Could we align this with the conventional ROS installation layout, or clarify the reasoning behind using the install/ subdirectory instead of the root-level setup file?

Thanks!

Depends on what you are trying to do and how Ros was installed.

1. /opt/ros/$ROS_DISTRO/setup.bash => the installation is from pre-built packages ie when you install via apt - if you follow the tutorial at https://docs.ros.org/en/kilted/Installation/Ubuntu-Install-Debs.html, then this is where it will be installed - note this is a system wide installation

2. You will use /opt/ros/$ROS_DISTRO/install/setup.bash when you are building from source or creating specific packages for your use. In jetson-containers you are building ros2 packages from scratch.

Another scenario could be when you have installed system wide package as in the first case but you want to run a special package then you would use this second option. So this could be a scenario like the one below

• You are a developer working on custom ROS packages or a custom ROS distribution.
• You built ROS from source (e.g., in a workspace) and installed it to /opt/ros/$ROS_DISTRO/install/.
• You want to use the locally built and installed ROS packages instead of (or in addition to) the system-wide ROS installation.

Hope this helps
