ROS2 moving workspaces

edit

Hi! A short and simple question. I'm noticing that my Linux /usr directory (~) is filling up. I would therefore like to move all my ROS workspaces into a subfolder called (something like) ROS_WSS. However, I've noticed that one does not simply move a workspace.

My experience is that moving workspaces around – after building them – is a hassle. I could do this in a brute force way, rebuild everything and debug etc. However, I would like to solve this in a time-efficient manner. Do you have any tips for how I can go about this?

TL;DR: I have built this:

home/
├─ usr/
│  ├─ ros2_foxy/
│  ├─ px4_ros_com_ros2/
│  ├─ Fast-RTPS-Gen/
│  ├─ FastDDS/

I want this, without everything going bad.

home/
├─ usr/
│  ├─ ROS2_WSs/
│  │  ├─ ros2_foxy/
│  │  ├─ px4_ros_com_ros2/
│  │  ├─ Fast-RTPS-Gen/
│  │  ├─ FastDDS/

Note that px4_ros_com_ros2 depends on ros2_foxy
