Just a suggestion: Some motivating examples may help. Perhaps you can show 1. Initial state of the world (show with the help of a few ls) 2. A sequence of commands to change it 3. What the world looks like finally
And a brief description why this would be desirable. And how it compares with just using chroot. Most people here can perhaps read rc code more readily than elaborate explanations! In *BSD a jail is more than chroot since it can also get access to its own interfaces, networking stack, init process, devices etc. And it can't look at the state of another jail or the host. And another host on the net doesn't even know it is talking to a jail. To do something similar you will have to constrain each jail to see a subset of processes, give it its own /dev, /env etc. Not sure how you do this.
