systemd 201
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
