If the current root filesystem is a union, then allow pivot_root
only if it's last component is a root, which allows
pivot_root of union mount points. Here

Within a union mount point, there can be directories which don't

A particular case I hit is with a 3 layer union with a subdir union

directory in the middle layer from outside of this union, you hit the

Subject: Union mount readdir
This modifies the readdir()/getdents() routines to read directory
entries from toplevel and the lower directories of a union and present
a merged view.
The directory entries are read starting from the top
copied to the topmost union layer
first.
This patch uses the do_splice_direct() for doing the in-kernel file copy.

Here is another post of vfs based union mount implementation.
Union mount provides the filesytem namespace unification feature.
Unlike the traditional mounts which hide the contents of the mount point,
the union mount presents the merged view of the mount point and the
mounted filesytem.
