[Bug 1126560] [NEW] /etc/networking/* are executed multiple times

[Sworddragon]

Public bug reported:

I'm using Ubuntu 13.04 dev with ifupdown 0.7.5ubuntu2. I have noticed
that on booting my system in /etc/networking the scripts in if-pre-up.d
and if-up.d are executed multiple times. On my observations I have
noticed that they can even be executed parallelized. I have logged what
happened on a boot:

1. The content of /etc/networking/if-pre-up.d is executed parallelized 2 times.
2. After they have finished the content of /etc/networking/if-up.d is excuted.
3. Then the content of /etc/networking/if-pre-up.d is excuted again.
4. At last the content of /etc/networking/if-up.d is executed again too.

As a summary: The content of /etc/networking/if-pre-up.d was executed
3times and /etc/networking/if-up.d 2 times.
