With post-up no longer available under the network service, isn't NM the 
only way to run scripts on interface up?

I tried that. With onboot=yes, the interfaces do not come up in runlevel 
3. Even on my laptop, neither wired nor wireless connections come up 
unless I start X. I think the problem is that NM doesn't bring up 
anything unless it has a "client". And the clients are all X clients, 
except nmcli.

Is that wrong?

nmcli con list

** (process:25290): WARNING **: get_all_cb: couldn't retrieve system 
settings properties: (2) The name 
org.freedesktop.NetworkManagerSystemSettings was not provided by any 
.service files.

I think the problem is that this command lists "configured" connections. 
But I can't configure the connection without NAMEs (id) or UUIDs (uuid)!

But how do I find out the id's or uuid's? Where are they stored? Does 
udev have them someplace?
