I have a single physical network interface (and a loopback):
root@fedora:~# networkctl
IDX LINK TYPE OPERATIONAL SETUP
1 lo loopback carrier unmanaged
2 enp2s0 ether routable unmanaged
2 links listed.
There are no other interfaces. As I mentioned before, this is a very
simple, "cattle" machine set up via unattended kickstart. And I'd much
rather *not* have to turn it into a fragile, high-maintenance "pet"...
With systemd-networkd-wait-online.service enabled,
systemd-networkd.service itself ends up active/running happily,
but systemd-networkd-wait-online.service fails with:
systemd-networkd-wait-online[550]: Timeout occurred while waiting
for network connectivity.
Unless there's anything glaringly obvious that I'm too silly to notice
(in which case a swift kick in the ribs would be much appreciated),
I'll most likely move this conversation to the systemd mailing list,
and (in parallel) ask the sendmail maintainers if there's anything
that can be done on that front, orthogonally to this...
I honestly didn't expect my use case to be *that* far off the beaten
path, yet here we are... :P
Thanks again to everyone involved,
