If you've ever worked with Jailkit, or have some general experience with chroot jails, and you use CentOS 7, please have a look at the package I just published in our bleeding edge repo here:
This package should, theoretically, work for pretty much everything documented on the Jailkit home page, without needing to make package-level changes (i.e. config files need to change, as documented, but it should Just Work, once the config is right).
Those docs are here: http://olivier.sessink.nl/jailkit/
Once we've worked out any issues with the CentOS packages, we'll get it packaged for Debian and Ubuntu, as well. Note that this is not recommended for folks who aren't familiar with chroot jails, or don't understand the security risks inherent in their use. Chroot jails are dangerous tools. So, either poke at this on a development server, or know what you're doing, or don't mess with it at all!
Something to note: The chrootsh binary in this package uses capabilities, rather than being setuid; this is safer, but, I haven't tested every use case to know if everything that needs to have elevated privileges is setup right.
