Thanks Otto, packages are building now.

There is an oddity I noticed in the .debdiffs I generated: there are /tmp/*/... files changed in the packages. From the trusty package:

I suspect this means they've been part of the packages for a little while now, so not introduced with these changes, so I went ahead and started the builds anyway. But if you could investigate these and hopefully stop them from being included in the future, that'd be best.

I also found that 'uscan' isn't particularly useful for performing security updates -- it mangles your useful changelog with a generic changelog and ran a large amount of what felt like magic commands. I decided to skip uscan and just follow the usual process we've worked out: download the tarball, check the signature, unpack, rename the tarball and directory, delete upstream''s debian/ directory, cp -a the old debian/ directory, apply your patch, and build. (Repeating it mostly for Seth in the future.) (Thanks again for asking the MariaDB team to use gpg signatures!)

Thanks
