Network boot fails in dracut-initqueue due to nm-online wrongly pretend that the network is connected

Hi.

For information, I made this buzilla this morning:

https://bugzilla.redhat.com/show_bug.cgi?id=2104398

(I did similar for Fedora-34).

I wonder if there is a single case where nm-online is useful :-(

Yes there are use cases where this is needed.
Some times network is need to complete boot in I tire before switching the the main disk.

For example Luke unlocking:

Of course, but to be clearer: doing that with nm-online does NOT work.

In my case (network boot), nm-online terminates BEFORE the default gateway
is reachable. As a consequence downloading the install image
(Server/x86_64/os//images/install.img) fails.

My workaround is to replace nm-online by a loop waiting for the gateway to be
reachable.

The network-online.target which nm-online is before only says that the interface has a configured ip address.
It does not test connectivity.

Having said that I am very surprised that the gateway is not reachable.
At least in small networks the gateway is the same host that is the dhcp server and thus will be reachable.

What you are doing with waiting until you can access the remote host seems like the required solution.
