At the end of the day a chroot gives you boundaries. Once inside a chroot
an application/developer can't hose the base of PASE by doing something
silly (installing rpms that ruin another developer's environment).

I like to think of chroot containers as being similar to how I use
VirtualBox for testing Linux Distros.  I can easily spin one up to try
something.  I can keep it as long as I want.  I can delete it and start
over if I screwed it up.

Another big advantage is you can script the creation of developer and
production chroot containers, and that script can be stored in Git so your
environments are change managed.
