systemd

Time to move on from using the init daemon to manage starting and stopping processes and services.

systemd is a system management daemon that replaces init.d and is available on most distributions.

Fedora documentation can be found here.

To create a new service, create a new configuration file /etc/systemd/system/foo.service (note that absolute path names are required, even for interpreters etc.):
