Some newer distributions have replaced the old SYS-V style of initialization daemons (and scripts) with an alternative called Systemd.

Pacemaker is able to manage these services if they are present.

Instead of init scripts, systemd has unit files. Generally the services (or unit files) are provided by the OS/distribution but there are some instructions for converting from init scripts at: http://0pointer.de/blog/projects/systemd-for-admins-3.html
