# ASSERT(<prefix> == /usr)
# ros-workspace installs its setup scripts under <prefix>, which is an unnatural location when <prefix> is /usr. Move them to be
# under <sysconfdir>/profile.d/ros and create "ros_" prefixed symlinks to them under <bindir>. If "ros-implicit-workspace"
# appears in DISTRO_FEATURES, create a ros.sh that sources ros/setup.sh, thereby setting up the ROS workspace for every login
# shell.
