systemd-getty-generator — Generator for enabling getty instances on the console
/usr/lib/systemd/system-generators/systemd-getty-generator
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 enable console-getty.service
for
/dev/console
, and
container-getty@.service
instances for
additional container pseudo TTYs as requested by the container
manager (see Container
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 console=
to get both
kernel messages and a getty prompt on a serial TTY. See kernel-parameters.txt
for more information on the console=
kernel
parameter.
systemd-getty-generator
implements
systemd.generator(7).
Further information about configuration of gettys can be found in systemd for Administrators, Part XVI: Gettys on Serial Consoles (and Elsewhere).
