As we have parity at the moment, I'm all for having only one build. Keeping both lt-vexpress and vexpress will only confuse our users. Now that we've got a proven build from linux-linaro, I'm happy to drop the LT builds and have only the linux-linaro ones. Then, any failures that we wouldn't have expected would be defects/regressions (when compared to what happens if using the LT tree). I don't speak for the other LTs of course, all of whom have a more complex situation than my team. > Cheers, > -- > Ricardo Salveti de Araujo >
