I'm using the prebuilt BRLTTY package from Fedora: brltty-6.8-4.fc43.x86_64, in which you have the file /usr/lib/systemd/system/brltty.service. Systemd is starting BRLTTY. The file looks like:

```
[Unit]
Description=Braille display driver for Linux/Unix
Before=getty.target display-manager.service

[Service]
Type=forking
ExecStart=/usr/bin/brltty

[Install]
WantedBy=default.target emergency.target rescue.target
```

Let me add that when BRLTTY on initrd starts, I hear the alerts.

Yes,
l-wx------ 1 root root 64 april  6 09:45 10 -> /dev/tty0
and
l-wx------ 1 root root 64 april  6 09:45 23 -> /dev/tty0
