upstart -> udev emits events

[navern]

Hello,

I am using upstart extensively.

There is default job, which is emitting upstart events from udev events. 
I want to discard events for specific INTERFACE names(with glob mask), 
something like this: and ! INTERFACE ~= "veth*". I don't want upstart 
emitting events when there is new device with name veth*(for example: 
vethd76b953)

Reason to do this: we are using docker with watchdog for containers. And 
if there is container which is constantly stopped and turning on again 
-> server goes down with multiple /proc/self/fd9 processes.


Can someone help me with this or point me to some documentation?
