The default
Systemrandom number seed is nowseed=rand(UInt). The motivation is that callingRandom.seed!prior toSystemconstruction will fixSystem.rngin a deterministic way. This may be helpful for writing reproducible Sunny scripts that sometimes also call Julia's task-local RNG.An underlying motivation is to make the doc builds exactly reproducible. This will hopefully allow for more compression on the
gh-pagesbranch, which already requires 160+ MB to store docs images, with repetition on every Sunny release. See also #233 (comment).
