+- Add chrony-pool-suse and chrony-pool-openSUSE subpackages that
+  preconfigure chrony to use NTP servers from the  respective
+  pools for SUSE and openSUSE (bsc#1156884, SLE-11424).
+- Add chrony-pool-empty to still allow installing chrony without
+  preconfigured servers.
+- Use iburst in the default pool statements to speed up initial
+  synchronisation (bsc#1172113).
