Forum Linux.debian/ubuntu initctl show-config networking

Bonjour,

Il y a quelque chose qui m'échappe avec cette commande.

Le script d'init nous dit,

vagrant@ubuntu:~$ cat /etc/init.d/networking 
#!/bin/sh -e
### BEGIN INIT INFO
# Provides:          networking ifupdown
# Required-Start:    mountkernfs $local_fs urandom
# Required-Stop:     $local_fs
# Default-Start:     S
# Default-Stop:      0 6
# Short-Description: Raise network interfaces.
# Description:       Prepare /run/network directory, ifstate file and raise network interfaces, or take them down.

Il n'y a pas de fichier d'override,

vagrant@ubuntu:~$ ll /etc/init.d/networking*
-rwxr-xr-x 1 root root 4479 Mar 20  2014 /etc/init.d/networking*

cf http://upstart.ubuntu.com/cookbook/#disabling-a-job-from-automatically-starting

Alors comment se fait il qu'upstart puisse me sortir autant de stanzas, puisqu'à priori celles ci n'existent pas..

vagrant@ubuntu:~$ initctl show-config networking
networking
  emits static-network-up
  emits net-device-up
  emits deconfiguring-networking
  start on (((local-filesystems and (stopped udevtrigger or container)) or runlevel [2345]) or stopped networking RESULT=failed PROCESS=post-stop EXIT_STATUS=100)
  stop on unmounted-remote-filesystems

??

Merci.
