Title:
  ovsdb-server.service needs a depedency on local-fs.target

Status in openvswitch package in Ubuntu:
  In Progress

Bug description:
  I recently just did a from-scratch install of Ubuntu 20.04 server
  edition and ran into issues with Open vSwitch and ZFS.  I attempted to
  use ZFS for all of /var only to find that ovsdb-server pre-empted my
  ZFS /var mount which caused it to crash when trying to read its
  configuration DB at/var/lib/openvswitch/conf.db  After much
  troubleshooting, the problem basically boils down to ovsdb-
  server.service needing a requirement on local-fs.target

  I then found a blog post on Open Cloud Blog
  (https://www.opencloudblog.com/?p=240) that contained a fix:

  The "After" line /lib/systemd/system/ovsdb-server.service needs the
  following changes:

      [Unit]
      Description=Open vSwitch Database Unit
      After=syslog.target network-pre.target dpdk.service local-fs.target
      Before=network.target networking.service
      PartOf=openvswitch-switch.service
      DefaultDependencies=no

      [Service]
      LimitNOFILE=1048576
      Type=forking
      Restart=on-failure
      EnvironmentFile=-/etc/default/openvswitch
      ExecStart=/usr/share/openvswitch/scripts/ovs-ctl \
                --no-ovs-vswitchd --no-monitor --system-id=random \
                start $OPTIONS
      ExecStop=/usr/share/openvswitch/scripts/ovs-ctl --no-ovs-vswitchd stop
      ExecReload=/usr/share/openvswitch/scripts/ovs-ctl --no-ovs-vswitchd \
                 --no-monitor restart $OPTIONS
      RuntimeDirectory=openvswitch
      RuntimeDirectoryMode=0755
