Aided by the efforts of the Reproducible Builds project [1], we’ve decided it’s
time to say that Debian must ship reproducible packages. Since yesterday, we
have enabled our migration software to block migration of new packages that
can’t be reproduced [2] or existing packages (in testing) that regress in
reproducibility.
