nm-wait-online exiting non-zero usually means, there was no network
connection configured by NM. This could have different reasons. E.g. for
WLAN the credentials could be stored in the user session and not be
available during boot.

If it's an ethernet connection, NM should establish the network
connection. It would be interesting to know, why it doesn't autoconnect.

Hm, could you send me a NetworkManager debug log from the boot

It was disabled in the past but I decided to enable it by default (as in
other distros, like Fedora or Ubuntu).
The reason for this is, that nm-wait-online is required to make remote
mounts work or services in general which depend on network-online.target
(aka $network).

Trading boot speed for that is acceptable imho and users who don't need
that can opt-out of nm-wait-online.
