I don’t understand the answer though.
The answer is if you’re depending on software that is closed and out of your control (aka. you have an Nvidia card) then you should have support expectations around that hardware and linux.
There are no GTS ISOs because we don’t have a reliable way to make ISOs (the ones we have now are workarounds) but that should be finished soon.
Both podman and docker are on the image, you could just use containers normally without using devcontainers if you want.
