systemd, the new init system created by Lennart Poettering, has added a couple of interesting features. First, he has added support for chroot-style isolation capabilities, but instead of chroot he used the powerful per-process filesystem and PID namespaces supported by the Linux kernel. Second, he has added a new tool, systemd-analyze, which shows how much time took each service to start, so you can optimize your bootup time easily. It can even create simple bootchart-style graphs.
