  28 .PP
  29 systemd\-getty\-generator
  30 is a generator that automatically instantiates
  31 serial\-getty@\&.service
  32 on the kernel console
  33 /dev/console
  34 if that is not directed to the virtual console subsystem\&. It will also instantiate
  35 serial\-getty@\&.service
  36 instances for virtualizer consoles, if execution in a virtualized environment is detected\&. Finally, it will instantiate
  37 container\-getty@\&.service
  38 instances for additional container pseudo TTYs as requested by the container manager (see
  39 \m[blue]\fBContainer Interface\fR\m[]\&\s-2\u[1]\d\s+2)\&. This should ensure that the user is shown a login prompt at the right place, regardless of which environment the system is started in\&. For example, it is sufficient to redirect the kernel console with a kernel command line argument such as
  40 \fIconsole=\fR
  41 to get both kernel messages and a getty prompt on a serial TTY\&. See
  42 \m[blue]\fBkernel\-parameters\&.txt\fR\m[]\&\s-2\u[2]\d\s+2
  43 for more information on the
  44 \fIconsole=\fR
  45 kernel parameter\&.
  46 .PP
  47 systemd\-getty\-generator
  48 implements the
  49 \m[blue]\fBgenerator specification\fR\m[]\&\s-2\u[3]\d\s+2\&.
