Looks like initramfs-tools leaks it via sysv-rc/file-rc/... Anyway, even if that wouldn't happen, you can also trigger it on the usual cmdline: ,---- [ simple demo ] | # echo $verbose | | # export verbose=foo | # /etc/init.d/networking restart | * Running /etc/init.d/networking restart is deprecated because it may not re-enable some interfaces ... (warning). | * Reconfiguring network interfaces... ifdown: Use --help for help | ifup: Use --help for help | failed. `---- regards, -mika-
