"This post's twist is that we'll be specifically approaching hiding data in ZFS mountpoints. For the purposes of our demonstration and experimentation, we'll assume that the version of ZFS we're using is the one that roughly corresponds with the date of this post. If any feature mentioned didn't work a year ago, or you're reading this in the future and find yourself disgusted with the lack of an "obvious" and simple solution that didn't exist yet, we beg your pardon. This blog is written in the present (over and over and over again), edited in the very near relative-future and published before the aforementioned activities become distant recollections from the past ;)

"Again, you can refer to our previous post on finding space hogs on multiple-overlay mountpoints if you want to look into that aspect a little bit deeper. Also, we'll be using the /usr/local overlay mount, mounted on top of /usr, for our models."
