[Bug 1429140] [NEW] lxc-net upstart script fails on nonexistent iptables rules

[Daniel Dehennin]

Public bug reported:

Hello,

On Trusty, the stop of lxc-net fails if the iptables rules are not
present.

I added “exec >> /tmp/lxc-net.log 2>&1” at the beginning of pre-start
and post-stop and get:

    iptables: Bad rule (does a matching rule exist in that chain?).

On Precise, a “|| true” was added to avoid errors.

I attach a patch to disable exit on failing iptables call.

Regards.
