After upgrade to vivid, my system takes nearly 4 minutes to boot. This appears to be related to the new systemd unit ordering.

[Unit]
Description=Open vSwitch
After=network.target openvswitch-nonetwork.service
...

root@mystic:/lib/systemd/system# systemd-analyze blame | head
      2min 233ms ifup-wait-all-auto.service
...

Open vSwitch is being started after the network, but the network needs Open vSwitch to start since my host traffic is flowing through the bridge:

root@mystic:/lib/systemd/system# ovs-vsctl show
838a8aa4-4811-447d-8dcc-dbb675b78968
    Bridge "br0"
        Port "br0"
            tag: 1
            Interface "br0"
                type: internal
        Port "vlan121"
            tag: 121
            Interface "vlan121"
                type: internal
        Port "eth0"
            tag: 1
            Interface "eth0"
    ovs_version: "2.3.1"

The interfaces do eventually start correctly, but only after the long timeout above.
