Because the Linux VFS doesn't (yet) provide the generic operations that
a union filesystem needs. If you look at the aufs config options and
the code, you will see that it needs to handle various filesystems
specially, and it needs to work around various limitations of the VFS.

How that does that show that aufs is good?

Valerie has proposed changes to the VFS to make 'union mounts' work.
Union mounts would be a new type of filesystem-mount, rather than a
new filesystem.
