# Takes a boolean argument or the constants error and auto. Can be also specified without an argument, with the same effect as a positive boolean. If enabled, the systemd manager (PID 1) shows
# terse service status updates on the console during bootup. With error, only messages about failures are shown, but boot is otherwise quiet. auto behaves like false until there is a significant
# delay in boot. Defaults to enabled, unless quiet is passed as kernel command line option, in which case it defaults to error.
