systemd-getty-generator — Generator for enabling getty instances on the console
systemd-getty-generator is a generator that automatically instantiates
serial-getty@.service on the kernel console(s), if they can function as ttys and are
not provided by the virtual console subsystem. It will also instantiate
serial-getty@.service instances for virtualizer consoles, if execution in a
virtualized environment is detected. If execution in a container environment is detected, it will instead
container-getty@.service instances for additional container pseudo TTYs as requested
by the container manager (see
Interface). 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
get both kernel messages and a getty prompt on a serial TTY. See
for more information on the
console= kernel parameter.
Further information about configuration of gettys can be found in systemd for Administrators, Part XVI: Gettys on Serial Consoles (and Elsewhere).
