Comment 27 for bug 336736

Eric, I think you have missed the point. Using "pre-up" scripts is what this
bug is about.

"pre-up" script functionality has been removed.

Marlon was asking to how to load iptable configs before an interface comes
up without using "pre-up" scripts.

I had a similar issue, but the only thing I could think of was to hand-edit
the if-up scripts to do what I want - now that's ugly.
