The following non-security bugs were fixed: - Update to release 9.16.31 (jsc#SLE-24600). - Logrotation broken since dropping chroot (bsc#1200685). - A non-existent initialization script (eg a leftorver "createNamedConfInclude" in /etc/sysconfig/named) may cause named not to start. A warning message is printed in named.prep and the fact is ignored. Also, the return value of a failed script was not handled properly causing a failed script to not prevent named to start. This is now fixed properly.
