56 <para><filename>systemd-getty-generator</filename> is
57 a generator that automatically instantiates
58 <filename>serial-getty@.service</filename> on the
59 kernel console <filename>/dev/console</filename> if
60 that is not directed to the virtual console
61 subsystem. It will also instantiate
62 <filename>serial-getty@.service</filename> instances
63 for virtualizer consoles, if execution in a
64 virtualized environment is detected. This should
65 ensure that the user is shown a login prompt at the
66 right place, regardless in which environment the
67 system is started. For example, it is sufficient to
68 redirect the kernel console with a kernel command line
69 argument such as <varname>console=</varname> to get
70 both kernel messages and a getty prompt on a serial
