Package: ifupdown

Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
ifdown does not correctly handle excluded interfaces passed in
$EXCLUDE_INTERFACES:
# EXCLUDE_INTERFACES="lo" /sbin/ifdown lo --read-environment -n
run-parts /etc/network/if-down.d
ip link set dev lo down
run-parts /etc/network/if-post-down.d
This appears to be caused by an issue copying the value of the
environment variable into excludint
*** End of the template - remove these template lines ***

# Cloud images dynamically generate config fragments for newly

# and /etc/network/cloud-ifupdown-helper. Dynamically generated
# configuration fragments are stored in /run:
source-directory /run/network/interfaces.d
--- /etc/network/interfaces.d/50-cloud-init:
# This file is generated from information provided by the datasource. Changes
# to it will not persist across an instance reboot. To disable cloud-init's
# network configuration capabilities, write a file
# /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following:
# network: {config: disabled}
