The configuration file "filer.toml" is read from ".", "$HOME/.seaweedfs/", "/usr/local/etc/seaweedfs/", or "/etc/seaweedfs/", in that order.
If the "filer.toml" is not found, an embedded filer store will be created under "-defaultStoreDir".
The example filer.toml configuration file can be generated by "weed scaffold -config=filer"
