Comment 8 for bug 1300367

Thank you for the patch!

Unfortunately using rsync's internal zlib violates policy section 4.13 (see in particular footnote 31 for rationale): http://people.canonical.com/~cjwatson/ubuntu-policy/policy.html/ch-source.html#s-embeddedfiles

For example: if a security vulnerability were found in zlib, then the security team expects to be able to fix it once in the archive. If we used rsync's internal zlib, then it would escape being fixed, and this would be dangerous.

However, from the changelog I see the Debian does the same thing:

  * revert to using included zlib as there have been numerous reports of failed
    transfers when using -z with the separate zlib.

So perhaps we need to make an exception in this case.

To update Trusty, we need to follow the SRU procedure documented here: https://wiki.ubuntu.com/StableReleaseUpdates#Procedure and submit the patch for sponsoring as described in the link from there. Please could you see how far you can get with this?
