Many thanks
I have tried to implement it but was not able to get a stable behavior :
depending if my server is shutdown -r or poweroff I got different
behavior...
So I decided to start ovs on a script after my server boots...for now
perhaps it would be good to get something working as expected in the
future when using systemd
ps : I also realized that systemd-networkd doesn't like the fact that
some interface has no IP (the interface part of ovs bridge)
for now in systemd-networkd is mandatory to have and IP address or DHCP
on interface managed by systemd-networkd but in case of openvswith
sometimes we don't want that..

what do you think it would bring to add this oneshot service as I

If I remember correctly, fedora split this for the following reasons.
openvswitch service will start after network. But network will look
at ifcfg-* scripts. If one of those scripts has openvswitch device to
be configured, it can't start it because openvswitch is not yet started.
So Fedora, added the following:
https://github.com/openvswitch/ovs/blob/master/rhel/etc_sysconfig_network-scripts_ifup-ovs#L63
What the above does is that it will force start
openvswitch-nonetwork.service even before openvswitch.service starts.

It looks like Arch hasn't split the Open vSwitch service into
pre- and
post-network stages. Here's what Fedora does:
$ cat openvswitch.service
