### `ynh_systemd_config` is used to configure a systemd script for an app.
### It can be used for apps that use sysvinit (with adaptation) or systemd.
### Have a look at the app to be sure this app needs a systemd script.
### `ynh_systemd_config` will use the file conf/systemd.service
### If you're not using these lines:

#=================================================
# SETUP APPLICATION WITH CURL
#=================================================

### Use these lines only if the app installation needs to be finalized through
### web forms. We generally don't want to ask the final user,
### so we're going to use curl to automatically fill the fields and submit the
### forms.

# Set right permissions for curl install

# STORE THE CONFIG FILE CHECKSUM
#=================================================

### `ynh_store_file_checksum` is used to store the checksum of a file.
### That way, during the upgrade script, by using `ynh_backup_if_checksum_is_different`,
### you can make a backup of this file before modifying it again if the admin had modified it.

# Calculate and store the config file checksum into the app settings
#ynh_store_file_checksum "$final_path/CONFIG_FILE"

# SECURE FILES AND DIRECTORIES
#=================================================

### For security reason, any app should set the permissions to root: before anything else.
### Then, if write authorization is needed, any access should be given only to directories
### that really need such authorization.

# Set permissions to app files
chown -R root: $final_path

###		- Remove the section "BACKUP LOGROTATE" in the backup script
###		- Remove also the section "REMOVE LOGROTATE CONFIGURATION" in the remove script
###		- As well as the section "RESTORE THE LOGROTATE CONFIGURATION" in the restore script

# ADVERTISE SERVICE IN ADMIN PANEL
#=================================================

### `yunohost service add` is a CLI yunohost command to add a service in the admin panel.
### You'll find the service in the 'services' section of YunoHost admin panel.
### This CLI command would be useless if the app does not have any services (systemd or sysvinit)
### If you're not using these lines:
###		- You can remove these files in conf/.
###		- Remove the section "REMOVE SERVICE FROM ADMIN PANEL" in the remove script
###		- As well as the section "ADVERTISE SERVICE IN ADMIN PANEL" in the restore script

#yunohost service add $app --log "/var/log/$app/$app.log"
