[Unionfs] cow problem?

[Pásztor Lénárd Zoltán]

Sure. The mount comands:
mount -t tmpfs none /1
mount -t nfs st1:/base /2
mount -t unionfs -o dirs=/1=rw:/2=nfsro unionfs /root
mount -o move /1 /root/union/1
mount -o move /2 /root/union/2

It's interesting the unionfs line in /proc/mounts. The kernel reports
read-write both of the layers.
