I can union-mount tmpfs over nfs mounted fs, but if I try to mount --union two NFS filesystems I always get -EBUSY on second mount on the same mountpoint. Something along these lines: doesn't matter if I use --union on first mount, the result is always the same. mount <--union> -t nfs server:/export/system /mnt OK mount --union -t nfs server:/export/profile /mnt mount.nfs: /mnt is busy or already mounted I patched mount.nfs so it knows about MS_UNION, and strace shows me that it passes that flag to kernel.
