> The logic is based on the value of the client_variant variable. This variable is initialized to "server" and then can be overwritten by a POST request to /meta/client_variant ; which we can see in the logs.

I actually mixed up source variant and client variant. The former reflects the type of image that we are installing. The latter reflects whether we are running a TUI or desktop based install.

When installing drivers, we want the drivers installed to match the source variant and not the client variant.

Therefore, the call to /meta/client_variant is not relevant, but the call to /source is what matters.
