There may be more than one opinion, but as the maintainer of a TLS
library in Debian I think it is a questionable tradeoff. At a minimum,
it would be preferable to use the version number instead of a fixed
constant for all releases.
MaraDNS does not support DNSSEC so the program may not use entropy for
keys. Either way, I'd rather use an unreproducible build than,
accidentally, a known number series to encrypt secrets. Can one patch
out the constant entirely so it is no longer available?
The upstream website says: "People like MaraDNS because itâ€™s ...
remarkably secure." [1] Since many distributions have the same issue,
upstream could perhaps offer the patch as a build switch to enable a
build-time seed only when needed.
Thank you for your hard work on Guix! As a newbie I'll say, what a
great distro. Thanks, everyone!
Kind regards,
Felix Lechner
