If you define a unit, and either systemd or a package in systemd.packages already provides that unit, then we now generate a file /etc/systemd/system/<unit>.d/overrides.conf. This makes it possible to use upstream units, while allowing them to be customised from the NixOS configuration. For instance, the module nix-daemon.nix now uses the units provided by the Nix package. And all unit definitions that duplicated upstream systemd units are finally gone. This makes the baseUnit option unnecessary, so I've removed it.

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>.
