Here is another post of the VFS based union mount implementation.
Is there any chance this will support NFS? 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:
doesnt 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.
