I agree, this seems to say to me that NetworkManager should run after<br>
network.pre-target, and glean@enp1s0 should be running before it.<br>
<br>
The glean@enp1s0.service is set as oneshot [1] which should prevent<br>
network-pre.target being reached until it exits:<br>
<br>
oneshot ... [the] service manager will consider the unit up after the<br>
main process exits. It will then start follow-up units.<br>
<br>
To the best of my knowledge the dependencies are correct; but if you<br>
go through the "git log" of the project you can find some history of<br>
us thinking ordering was correct and finding issues.<br>

The glean script doesn't run asynchronously in any way (at least not<br>
on purpose!). I can't see any way it could exit before the ifcfg file<br>
is written out.<br>

The way NM support works is writing out this file which is read by the<br>
NM ifcfg-rh plugin [2]. AFAIK that's built-in to NM so would not be<br>
missing, and I think you'd have to go to effort to manually edit<br>
/etc/NetworkManager/conf.d/99-main-plugins.conf to have it ignored.<br>
<br>
I'm afraid that's overall not much help. Are you sure there isn't an<br>
errant dhclient running somehow that grabs a different address? Does<br>
it get the correct address on reboot; implying the ifcfg- file is read<br>
correctly but somehow isn't in place before NetworkManager starts?<br>
