Union mounts was named "writable overlays" for one release in an
attempt to get away from the "arbitrary union of file systems" idea.
I think it helped, but went back to union mounts since it was more
familiar and made prettier function names.
The config option for union mounts says:
Union mounts allow you to mount a transparent writable layer over a
read-only file system, for example, an ext3 partition on a hard drive
over a CD-ROM root file system image.
