I know that's one of the features that DragonflyBSD has had for a while. I've never found much documentation surrounding the issue, but it's always been referred to as something that helps administrators set up different environments for different users. When users need to share most of an environment but with a few exceptions, you can just use a variant symlink for the differences, instead of setting up a jail and sharing everything else some other way.
