I've found one comment "./sddm.scm: ;; should be factored out into system-auth" that maybe suggests such a guix configuration already exists somewhere, but I can't find it. I'm not sure how to proceed. --Sig_/1y0cg8UfSKTM1GQP62WBwGC Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEEds7GsXJ0tGXALbPZ5xo1VCwwuqUFAlzAlXwACgkQ5xo1VCww uqW1Rwf9H0LbOjqUyXl3s3jLwKKuxVhF8NfZVqZyXu1KR9cJPTVC6o+ObgDypSVV GHJ0A8QPS5R4YSmwDmX29LyWuLYeurapiZSB5sKdEcQhSkJkWTemvatwTG1FZ3j5 s3+JJIvCfblnyvXo64SdqcACDiIKnKYaksRrUfcGSpzn6rxEsMbOrALKeLhW8sFL zAK3XIyh88w3IQzcfqoQgeB52lTYq0UfU1TrbXSJuAebiUR3y2+ebjVioO7Q5jnp iDQ/WFWG2pkN6VQicUg9G7BGkSDfmWhZZM/SpwzPyp0U9Tpqy+CDQN3FHMhM1tku x+2KF/eoSEI2NyCJC6PE5YMsClR/eQ== =XucN -----END PGP SIGNATURE----- --Sig_/1y0cg8UfSKTM1GQP62WBwGC--
