Anyone knows how Nix deals with that? Providing that the more important builds/architectures are prioritised, I don't think it's an all or nothing situation. For build farms providing substitutes, it's more about the time taken to catch up with changes. When I've tried emulation, I've found there are too many errors that only occur when emulating. --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQKlBAEBCgCPFiEEPonu50WOcg2XVOCyXiijOwuE9XcFAmAB1xlfFIAAAAAALgAo aXNzdWVyLWZwckBub3RhdGlvbnMub3BlbnBncC5maWZ0aGhvcnNlbWFuLm5ldDNF ODlFRUU3NDU4RTcyMEQ5NzU0RTBCMjVFMjhBMzNCMEI4NEY1NzcRHG1haWxAY2Jh aW5lcy5uZXQACgkQXiijOwuE9Xc7zA//UoiZckP5RkrwqkEfIaBRMrds9hMoR77O MQmRkidWRMjHlKrBf5hQ6TAwGkGv1Nz3Q1NJZQm6f04WPq2+EpLyyPwrafV/cW0U xj9+bUTXftQKL8DDTZJfiE9IcNuGhliTGgnEmYG1lLu6XQgCXVaHneHpURlavsj2 ctK0JOvvFyFfW53EbK1oWBjkJGq047wTmgbGZ6OS18VXWoC2jCOFJAVKBMYebTYA 5qAh/PKKXJIadKDFEDIEIiYmXw47vaKs1IOeEyy4TNNivtDzT1ObseGjIeGs0GlB 5LsPvztd0VcyvunZaxbKxtFxnv9Kxit51r1e537orO3L9hFgnrCITBOwp5/ZKj+2 X8qv65WHrYiNbqvwz0Cntl/Qezt1XuqHLcBD39gEb8aW3yQwYR3V+c3jKv56xQWj kh++qDSbLrcOsSR1K9dbrRjz5iNV9NxBegLduvL8kEccKVF1928E+WfJjCusbnWn 8OOwtpFVsC92uYcWPSeUEezu6yhf3qhvtV4H9a2UpzM+LPKu+/hQkaU+hIw3KJEP oS9RSNhAhnWeBlMOnDmu35Qjhg47E6Djlfe0wxHHsS0N13rTEOZBODPubuzraEZn WQUDJP2zYoHYOAqbDMZ+3FkpcBlG27kpJR7wHHkcmdZeFKf7UNII013aAV/dKIG2 Q+E9PQ8rxdM= =3EcM -----END PGP SIGNATURE----- --=-=-=--
