it uses might cause problems while scanning the library from the web UI. To do
so, edit the `/etc/apache2/envvars` file, comment the line `export LANG=C` and
uncomment the `. /etc/default/locale` line. Then you can restart _Apache_:
$ systemctl restart apache2

## Watching library changes
## Running the daemon
Instead of manually running a scan every time your library changes, you can run
a watcher that will listen to any library change and update the database
accordingly.
_Supysonic_ comes with an optional daemon service that currently provides the
following features:
- background scans
- library changes detection
The watcher is `supysonic-watcher`, it is a non-exiting process. If you want to
First of all, the daemon allows running backgrounds scans, meaning you can start
scans from the CLI and do something else while it's scanning (otherwise the scan
will block the CLI until it's done).
Background scans also enable the web UI to run scans, while you have to use the
CLI to do so if you don't run the daemon.
Instead of manually running a scan every time your library changes, the daemon
can listen to any library change and update the database accordingly. This
watcher is started along with the daemon but can be disabled to only keep
background scans.
The daemon is `supysonic-daemon`, it is a non-exiting process. If you want to
keep it running in background, either use the old `nohup` or `screen` methods,
or start it as a simple _systemd_ unit (unit file not included).
It needs some additional dependencies which can be installed with the following
command:
$ pip install -e .[watcher]
or start it as a _systemd_ unit (see the very basic _supysonic-daemon.service_
file).
