I believe all those legal-info issues were due to a recent change I did
in the autobuilders: before each build, I'm removing 5 random tarballs
from the download directory. The idea is that by removing tarballs, the
autobuilders would be re-downloading them from time to time, and
therefore autobuilders will see if the upstream site has disappeared,
the URL has changed, or something (until now, a given tarball was
downloaded once forever, and so we were not necessarily seeing the
issues that our users were having in terms of download).

However, my autobuilder server runs 3 parallel builds, and they share
the same download directory. So what was probably happening is that a
given build uses a tarball, the builds is fine, but then before the end
of this build, another build got started, and removed a bunch of
tarballs, including one the former build was interested in. And bang
during the legal-info thing. It was probably not happening between
download/extract because the time window is much shorter, but between
extract and legal-info, the entire build takes place.

So I've fixed that by doing one separate download directory for each
parallel build instance. Each build instance is removing 5 random
tarballs before each build, but from its own private download directory.

Best regards,

Thomas
