Comment 57 for bug 2065180

> The proposal in comment #2065180-44 is interesting. That would address user hooks. But what about hooks shipped by packages outside the Ubuntu archive?

We don't support packages shipped outside the Ubuntu archive. If they break, they break.

But it's not *hugegly* likely that they'll break, either, so this would only impose a small chance of regression on people using an unsupported configuration.
