I wanted to use ResilioSync to sync up my .torrent download folder on the desktop to the rwatch folder on the seedbox. A
ls -l in the /home/quick folder reveals that the ResilioSync folder Quickbox wants you to use (sync_folder) has a different group and permissions compared to the other folders. A
chmod 775 rwatch isn't enough. I wasn't able to add rwatch as a sync folder until I changed the user that ResilioSync was running under from rslsync to quick.
My suggestion is that it would be much easier to add folders if the user was changed from rslsync to quick. This would also place ResilioSync's config files in the user's .config directory and take precedence over /etc/resilio-sync/config.json.
