I'm not the person to help with NM, but in the absence of other

this would suggest a cause. Do you need the network before your login
prompt appears or not? If not, it looks like systemd needs telling that.
I think this just came up in a contemporaneous thread here, but in a
disk-mounting context rather than networking.

You originally wrote "about 30 useless seconds". It is worth stating
whether that is a counted-down timeout period or just an estimate of
a period you have wait. (I'm assuming you've done nothing to increase
the flow of console messages when you boot.)

I have no idea whether the status of eth1 could have any bearing
because I don't know where one makes ones wishes known to NM,
not having used it.
