I have the ifupdown plugin disabled in
/etc/NetworkManager/NetworkManager.conf; however, I still see the
following in syslog:

Sep 20 12:34:12 x NetworkManager[20704]: <info>  monitoring ifupdown state file '/run/network/ifstate'.

thanks

Later in the same log, NetworkManager also tries to open that file:

Sep 20 12:34:12 x NetworkManager[20704]: <warn>  Error: failed to open /run/network/ifstate

Affects me. In the journal log I see “NetworkManager[885]: <warn> [1681591017.6980] Error: failed to open /run/network/ifstate”.  As this is not only a warning but also an error, who has done what wrong?  (I have 184 occurrences of “error” in the output of `journalctl -b`; I'd really wish to know which one is no more than a printf resulting from sloppy, careless programming and which one also leads to the end-user problems at hand, whichever they may be.)

I downgraded the log message from warn to info.

That said, I'd be happy to take a patch which disables the ifstate
monitoring completely, if the ifupdown plugin has been disabled.

Similar stuff in my log:

Apr 28 00:15:58 MyHost NetworkManager[970]: <info>  [1777328158.2966] monitoring ifupdown state file '/run/network/ifstate'.
…
Apr 28 00:15:59 MyHost NetworkManager[970]: <info>  [1777328159.0159] failed to open /run/network/ifstate


ifupdown was uninstalled recently, and there is no /run/network.
