Hello. I would like to propose a more lighweight variant for CAELinux. Instead of using XUbuntu, I would like to propose building it from the LFS (Linux from Scratch) project, thru with the system would be more light and secure. As for the desktop, I consider in between LXDE and LXQt. After this base would be ready and properly configured (with is securiy critical thing), the tools of the current distro could be integrated.
