Alternatively, use CLI flags to specify a config location.
Copy a config from the [tutorial](/tutorial) or the `cmd/sampleconf` directory to one of these locations and customize it to your setup.
## Runtime Directories

## Running the Daemon
All work zrepl done is performed by a daemon process.
All actual work zrepl does is performed by a daemon process.
There are no *rc(8)* or *systemd.service(5)* service definitions yet.
The daemon does not fork and writes all log output to stderr.
Logging is configurable via the config file. Please refer to the [logging documentation]({{< relref "configuration/logging.md" >}}).
```bash
zrepl daemon
```
FreeBSD ships with the *daemon(8)* utility which is also a good start for writing an *rc(8)* file:
```bash
daemon -o /var/log/zrepl.log \
-p /var/run/zrepl/daemon.pid \
zrepl --config /usr/local/etc/zrepl/zrepl.yml daemon
```
There are no *rc(8)* or *systemd.service(5)* service definitions yet. Note the *daemon(8)* utility on FreeBSD.
{{% notice info %}}
Make sure to read the first lines of log output after the daemon starts: if the daemon cannot create the [stdinserver]({{< relref "configuration/transports.md#stdinserver" >}}) sockets
in the runtime directory, it will complain but not terminate as other tasks such as taking periodic snapshots might still work and are equally important.
Make sure to actually monitor the error level output of zrepl: some configuration errors will not make the daemon exit.<br />
Example: if the daemon cannot create the [stdinserver]({{< relref "configuration/transports.md#stdinserver" >}}) sockets
in the runtime directory, it will emit an error message but not exit because other tasks such as periodic snapshots & pruning are of equal importance.
