The article mentions FreeBSD jails and how their chroot jail is a mini-virtualization.

For Linux there is OpenVZ and/or Linux-VServer... as well as the container features that have already made it into the mainline Linux kernel... and additional code that is expected to make it into the mainline kernel in the next year or so.

Anyway, if you want a quality isolation (and OS Virtualization as well), you can do so with OpenVZ and/or Linux-VServer. Of course both of those require a modified kernel... but they do work well, are mature, and offer additional features like resource management, separate root user and accounts, and in the case of OpenVZ, checkpointing (offline and online/live migration).
