Firstly note that this is more like bug #1432173. Adding this comment here since that is a duplicate of this one
I get : $ systemctl status -l ifup-wait-all-auto.service ● ifup-wait-all-auto.service - Wait for all "auto" /etc/network/interfaces to be up for network-online.target Loaded: loaded (/lib/systemd/system/ifup-wait-all-auto.service; static; vendor preset: enabled) Active: active (exited) since Mon 2015-11-16 07:33:22 IST; 27s ago Docs: man:interfaces(5) man:ifup(8) Process: 514 ExecStart=/bin/sh -ec for i in $(ifquery --list --exclude lo --allow auto); do INTERFACES="$INTERFACES$i "; done; [ -n "$INTERFACES" ] || exit 0; while ! ifquery --state $INTERFACES >/dev/null; do sleep 1; done; for i in $INTERFACES; do while [ -e /run/network/ifup-$i.pid ]; do sleep 0.2; done; done (code=exited, status=0/SUCCESS) Main PID: 514 (code=exited, status=0/SUCCESS) CGroup: /system.slice/ifup-wait-all-auto.service Nov 16 07:32:53 xxx systemd[1]: Starting Wait for all "auto" /etc/network/interfaces to be up for network-online.target...
