Just wondering… Well, since DGX OS is modded Ubuntu…some users might want to, for example, swap it for arch. Have anyone meddled with DGX OS and maybe tried out some perversions like that? I am really not sure how much it’s Ubuntu and how much it could be considered now as a separate DGX OS distro. I guess you could swap out arch linux kernel for it in theory it could work? ---

DGX OS is the tested, and supported operating system for running on Spark. Developers free to experiment with other Linux distributions, but NVIDIA diagnostics and workload are validated only on DGX OS. If service is needed, you may be asked to reimage back to DGX OS—the officially supported environment. ---
