Unfortunately the proper fix did not make it to the mainlie (it probably will
next stage1). Building kernel is however important. Can you please fill it in
and mark it as a regression? I think I will implement a hack and track everything
that refers user named labels and force it to partition 0. Ugly but probably
best we can do at the moment.
It would help to track it as a regression.
