## Taming the journal's size

Systemd's system journal's size can go out of control. There are some things you can do to keep it in control:

```shell
journalctl --vacuum-size=512M
journalctl --vacuum-time=4weeks
```

## Forwarding the journal to /dev/tty12

**You really want this? It's basically a leak available with a shortcut.**

This is very simple. Just create the file `/etc/systemd/journald.conf.d/fw-tty12.conf` and fill it like this:

```shell
[Journal]
ForwardToConsole=yes
TTYPath=/dev/tty12
MaxLevelConsole=info
```

Then, restart the service:

```shell
systemctl restart systemd-journald.service
```
