Subject: gnu: rsync: Use system zlib and popt libraries.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Reduce our likelihood of contracting security bugs at the expense of
compression ratio (in some cases) and compatibility with rsync≤3.1.1.

rsync@3.1.2 was released in 2014.  Time to upgrade your CentOS box.

* gnu/packages/rsync.scm (rsync)[inputs]: Add popt and zlib.
[arguments]: Use them.
