[Buildroot] [PATCH 07/15] package/connman: adapt to preset-all

["Jérémy ROSEN" <jeremy.rosen@smile.fr>]

Yes, the whole "*-wait-online" mechanism is a boot synchronisation thing.

The point is to delay starting of all network-facing daemon until
* either the network is up (DHCP dialog is done)
* or the network has failed (and won't be brought up at all during boot)

The exact implementation depends on your network-manager, so it might be
different
for NetworkManager, connman or systemd-networkd.

That being said, I have never heard of any of those "phoning home" They
just wait for the
end of the network configuration.

Moreover, since sysV, network-facing daemons have always been delayed after
the
network was up (through unit.d file ordering) and changing that might break
things in
subtle ways.

I'm pretty sure it's a bug, I'll leave them enable for v2, but we can
discuss it some more if you want...
