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?

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.
