  • I've been a heavy user of Linux vservers (see also: OpenVZ and the other one whose name I forget; and BSD 'jails') for a number of years. They are similar in concept to your chroot solution except much more convenient to use. They are lightweight because the virtual servers don't run their own kernels - they share the host kernel but with key structures like the process table partitioned into separate namespaces.
