Actually, I haven't quite figured out what this means. AIUI if an interface is defined in /e/n/i then NM shouldn't configure it anyway. Does it mean that if you define one in a "source-directory" directory, NM won't realise and so might try to configure it itself? > > but we don't know whether you're using "source-directory" or "source", > > for example. > > I'm using "source": > > # cat /etc/network/interfaces > # This file describes the network interfaces available on your system > # and how to activate them.

We also need to look at your evidence as to the configuration order actually executed. I'm not yet convinced that your /tmp/interfaces_test tells the right answer in view of the following statement: "When ifupdown is being called with the --all option, before doing anything to interfaces, if calls all the hook scripts (pre-up or down) with IFACE set to "--all", LOGICAL set to the current value of --allow parameter (or "auto" if it's not set), ADDRFAM="meta" and METHOD="none". After all the interfaces have been brought up or taken down, the appropriate scripts (up or post-down) are executed." That includes ifup -a of course. Cheers, David.
