Faster boot with host-only initramfs
This Fedora release builds an initramfs tailored especially for your computer hardware, allowing faster boot. If you change your machine or significant hardware, you might have to boot with the "Rescue" boot entry and execute "dracut --regenerate-all". If you want your initramfs to be hardware independent, install the "dracut-nohostonly" rpm package. If you don't want rescue images at all (like in virtual machines), install the "dracut-norescue" rpm package.
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.
