Modular service configuration with drop-in files
systemd will now look for configuration directives for a service as `/etc/sytemd/system/foobar.service.d/*.conf`, making site-specific changes easier to deploy and distribute .
graphing the boot process
- systemd-analyze can now use the GraphViz `dot` tool to generate graphs of the boot process. GraphViz can be installed with `yum install graphviz` and will create a representation of the full boot process with `systemd-analyze dot | dot -Tsvg > systemd.svg` More refined plots can be generated with the optional arguments "--order" "--require" "--from-pattern=" and "--to-pattern="
For more details and examples, see `man 1 systemd-analyze`.
Services with a PrivateTmp= directory defined in their configuration make use of a private temporary directory that is shared by all processes of the service. These temporary files are deleted when the service is stopped.
