I don't think you are right here. I dropped a script in /etc/network/*.d/ which dumps the environment variables and activated an interface using ifup/ifdown The relevant output is: /etc/network/if-down.d/debug PHASE=pre-down /etc/network/if-post-down.d/debug PHASE=post-down /etc/network/if-pre-up.d/debug PHASE=pre-up /etc/network/if-up.d/debug PHASE=post-up You see, there is no down resp. up PHASE for the hooks in there. Maybe you also understand, what I mean with that the names of the hook directories do not reflect the PHASE variable. > >> I'm a bit puzzled why you think that keeping down mapped >> to pre-down is preferrable. > > Because it only requires changing the way one package works > (network-manager) versus two (network-manager and ifupdown). > The scripts installed with those directory names (which are > useable as PHASE values) expect to run in a universal order > regardless of whether the interface is managed by > network-manager or spelled out in interfaces. I guess you misunderstood what I meant. Changing the mapping in 01ifupdown from NM's down -> post-down does not involve any modifications to ifupdown itself.
