Well, i can't use the pre-up direcrive without the iface statement. Or I can use one on the first vlan interface however it seems not very obvious decision to maintain it later.
You can actually put it on all of the interfaces that need the larger mtu; calling it repeatedly is a no-op.
I followed the advice by Pascal Hambourg (setting the iface statement to manual) and it worked.
That also works. At one time ifupdown didn't have interface dependencies so this was a potential gotcha in corner cases, but I think it should be fine now.
