Right now, yes. And that's completely and entirely down to NetworkManager
bringing interfaces up in an event-driven fashion, when link is detected.
Nothing at all to do with systemd. It seems to hit relatively few people,
because it appears to only be a problem when the NIC and the switch don't
establish an active link for much longer than 5 seconds. It's kind of
unreasonable for the link to take that long, IMHO. But, reasonable or not,
it happens with some managed switches. I think something similar is the
No managed switches here. Just some dumb switch with a bunch of stuff
plugged into it.
