Tty (virtual console) devices, in addition to the consoles on
|
|
which mingetty and syslogd run, that must be initialised.
|
|
Only useful if you have some program that you want to run on
|
|
some fixed console. For example, the NixOS installation CD
|
|
opens the manual in a web browser on console 7, so it sets
|
|
<option>boot.extraTTYs</option> to <literal>["tty7"]</literal>.
