ECDSA testing on staging

so right now for ECSA testing we need to pass --test-cert flag (webroot ?) and then also pass the path to --csr /path/to/ecdsagenerated-csrfile ?

or can we let letsencrypt client generate the csr file too ?

there’s no equivalent to cli.ini setting for rsa-key-size ? is that ignored in a cli.ini if you pass the path to --csr /path/to/ecdsagenerated-csrfile ?
