So, we really have two separate issues here, thus I cloned the bug to handle
them separately:
1.) network-manager does not support pre-up/pre-down scripts
2.) the current 01ifupdown script incorrectly maps the NM "down" event to the
ifupdown pre-down PHASE (running scripts in if-down.d). It should map the "down"
event to PHASE=post-down" and run the script in if-post-down.d
I have something like this in mind, to address 2.)
01ifupdown:
# Run the right scripts
case "$2" in
up)
export MODE="start"
export PHASE="post-up"
exec run-parts /etc/network/if-up.d
;;
down)
export MODE="stop"
export PHASE="post-down"
exec run-parts /etc/network/if-post-down.d
;;
# pre-up/pre-down not implemented. See
# https://bugzilla.gnome.org/show_bug.cgi?id=387832
# pre-up)
# export MODE="start"
# export PHASE="pre-up"
# exec run-parts /etc/network/if-pre-up.d
# ;;
# pre-down)
# export MODE="stop"
# export PHASE="pre-down"
# exec run-parts /etc/network/if-down.d
# ;;
*)
echo "$0: called with unknown action \`$2'" 1>&2
exit 1
;;
esac
So, regarding 2 resp. #562811, the fix is rather easy.
Regarding 1, support for pre-up/pre-down, it has to be noted that the version in
lenny shipped a custom patch, which basically changed NM's down event to
pre-down [2], and added a post-down and pre-up event.

[2] that's the reason why the current 01ifupdown script does not correctly map
the down event. The patch was dropped but 01ifupdown had not been updated
accordingly.
