|
|
systemd\-getty\-generator
|
|
is a generator that automatically instantiates
|
|
serial\-getty@\&.service
|
|
on the kernel console
|
|
/dev/console
|
|
if that is not directed to the virtual console subsystem\&. It will also instantiate
|
|
serial\-getty@\&.service
|
|
instances for virtualizer consoles, if execution in a virtualized environment is detected\&. Finally, it will instantiate
|
|
container\-getty@\&.service
|
|
instances for additional container pseudo TTYs as requested by the container manager (see
|
|
\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
|
|
\fIconsole=\fR
|
|
to get both kernel messages and a getty prompt on a serial TTY\&. See
|
|
\m[blue]\fBkernel\-parameters\&.txt\fR\m[]\&\s-2\u[2]\d\s+2
|
|
for more information on the
|
|
\fIconsole=\fR
|
|
kernel parameter\&.
