f220d83c | 55 | |
798d3a52 ZJS |
56 | <para><filename>systemd-getty-generator</filename> is a generator |
57 | that automatically instantiates | |
8522ee79 AJ |
58 | <filename>serial-getty@.service</filename> on the kernel |
59 | console(s), if they can function as ttys and are not provided by | |
60 | the virtual console subsystem. It will also instantiate | |
798d3a52 ZJS |
61 | <filename>serial-getty@.service</filename> instances for |
62 | virtualizer consoles, if execution in a virtualized environment is | |
8522ee79 AJ |
63 | detected. If execution in a container environment is detected, it |
64 | will instead enable <filename>console-getty.service</filename> for | |
65 | <filename>/dev/console</filename>, and | |
798d3a52 ZJS |
66 | <filename>container-getty@.service</filename> instances for |
67 | additional container pseudo TTYs as requested by the container | |
68 | manager (see <ulink | |
28a0ad81 | 69 | url="https://www.freedesktop.org/wiki/Software/systemd/ContainerInterface/"><filename>Container |
798d3a52 ZJS |
70 | Interface</filename></ulink>). This should ensure that the user is |
71 | shown a login prompt at the right place, regardless of which | |
72 | environment the system is started in. For example, it is | |
73 | sufficient to redirect the kernel console with a kernel command | |
74 | line argument such as <varname>console=</varname> to get both | |
75 | kernel messages and a getty prompt on a serial TTY. See <ulink | |
76 | url="https://www.kernel.org/doc/Documentation/kernel-parameters.txt"><filename>kernel-parameters.txt</filename></ulink> | |
77 | for more information on the <varname>console=</varname> kernel | |
78 | parameter.</para> | |
