    https:\/\/wiki.archlinux.org\/index.php\/Systemd#Handling_dependencies<\/p>\n

    With systemd, dependencies can be resolved by designing the unit files correctly. The most typical case is that the unit A requires the unit B to be running before A is started. In that case add Requires=B and After=B to the [Unit] section of A. If the dependency is optional, add Wants=B and After=B instead. Note that Wants= and Requires= do not imply After=, meaning that if After= is not specified, the two units will be started in parallel. <\/p><\/div>\n<\/p><\/div>\n<\/li>\n
