# @brief Helper utility to aid with mounting RClone S3 buckets to the file system
# @description
#     This script is a helper utility to assist a system service that ensures various
#     RClone S3 mounts are mounted properly. For more information, take a look at the
#     RClone files stored in `~/.config/rclone`.

### Mount variables

### Path definitions
if [ "$TYPE" = 'user' ]; then

### Define rcloneignore location

chmod -f 600 "$CONFIG_FOLDER/rclone.conf"
