   An update that solves one vulnerability and has 6 fixes is
   now available.

Description:

   This update for cloud-init fixes the following issues:

   Security issue fixed:

   - CVE-2019-0816: Fixed the unnecessary extra ssh keys that were added to
     authorized_keys (bsc#1129124).

   Non-security issues fixed:

   - Add cloud-init-renderer-detect.patch (bsc#1154092, bsc#1142988)
     + Short curcuit the conditional for identifying the sysconfig renderer.
       If we find ifup/ifdown accept the renderer as available.
