This update fixes the following issues for sysconfig:
- bnc#780644:
* Execute netconfig/ntp-runtime update in background, so dhcp post processing works faster when ntpdc needs a while
* Fixed netconfig/ntp-runtime to not use try-restart as its start may block for a while, so just add servers ourself. When ntpd is not running (not yet started), the init script will pickup our servers later
* Fixed ifup-dhcp to not start dhcp clients too early or they may be unable to send packets and just increase resend time. Instead, load af_packet module early and wait for link ready
- bnc#785240, bnc#780644: Changed rcnetwork to not report dhcp in background to systemd. You may set DHCLIENT_MODIFY_SMB_CONF to "no" in /etc/sysconfig/network/dhcp as the samba/cifs hooks make systemctl calls to reload/restart nmb and other services which block (systemd deadlock) ifup scripts for a long time.
- bnc#716652: Fixed to not report failure while setting unsupported power management option in ifup-wireless as the support and features depends on the driver
- bnc#784952: Fixed to check and reject too long interface names or names with suspect characters, do not wait when creation of virtual interface name fails
