Package: ifupdown
Version: 0.6.7
Severity: important
I noticed that ifupdown doesn't use if-post-down.d-scripts and/or
post-down-stanzas from interfaces file when it's called by udev's
hotplug events. I'm using madwifi-ng with wpa_supplicant.
Reproduciable with other hotpluggable hardware?
===========================================================
I use following interfaces file:
auto lo
iface lo inet loopback
allow-hotplug ath0
iface ath0 inet dhcp
pre-up echo bugtrap_pre-up
up echo bugtrap_up
down echo bugtrap_down
post-down echo bugtrap_post-down
wpa-driver madwifi
wpa-conf /etc/wpa_supplicant.conf
iface eth0 inet static
address 192.168.0.4
netmask 255.255.255.0
network 192.168.0.0
broadcast 192.168.0.255
gateway 192.168.0.1
dns-nameservers 130.132.1.1 130.132.1.22
and here is grepped log from ifdown:
sudo strace -f -o ifdown.strace ifdown ath0
grep -E "execv.*(run-p|bugtrap)" ifdown.strace

and log from pcmia card eject:
