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>.
