Comment 1 for bug 1169644

This echoes a conversation I was having with Ryan Harkin this morning - it's probably about time we re-baselined all master images in the lab. The current baseline is 12.02, and it's all a bit of a mess because some boards (eg vexpress, snowball) are baselined to 13.03, others to 12.06 etc. I'll make the blanket change and update the Arndales, and then over time migrate all the other boards. Maybe make it a backlog BP that we can assign to Matt when he joins.
