Hrm. I hear Efraim say better to have unique randomness and no substitutes, and I hear Tobias say more or less it's ok as long as upstream is right about it being ok to embed a specific prime as other random numbers get mixed in at runtime... I have a slight inclination towards making it non-substituteable, but I may just be enamored of this as an interesting solution that most distributions do not really have the option of taking. :) Anyone else able to weigh in? Or actually review the code? If we can't find someone to review the code, seems like non-substitutable is the safest approach ... at the guaranteed loss of reproducibility. :/ Would love to resolve this issue one way or another. live well, vagrant --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iHUEARYKAB0WIQRlgHNhO/zFx+LkXUXcUY/If5cWqgUCYszeIwAKCRDcUY/If5cW ql7cAP9jVeFBlV6j6irzlQNFZB7q8o5KNHEWmLm65MiCybwOCQEA4FYeCPSTan/E iD/htreXurJAMCYKRsykPQg2oPN+cwQ= =MGKA -----END PGP SIGNATURE----- --=-=-=--
