OpeneElec Kodi hacking - creating music catalog

Systemd CIFS mount

[Unit]
 Description=cifs mount script
 Requires=network-online.service

Important: this file must be renamed to mountpoint.mount where mountpoint, is the FULL path where the share will be mounted. Slashes "/" MUST BE REPLACED with dashes "-" with .mount as extension. This means, if we want mount to "/storage/music/rock" (see above "Where=/storage/music/rock") then this file must be renamed to 'storage-music-rock.mount'. This is only for the filename! not for the What= and Where= sections!

Script that maps file by the first two letters

/storage/.config/create_symb_links.sh chmod +s /storage/.config/create_symb_links.sh

#!/bin/bash

  echo -e "\nUsage:\n$0 [src-dir] [links-dir]\n  src-dir\tsource directory to be scanned\n  links-dir\tfull path to target directory where symbolic links will be created\n\n" 
  echo -e "e.g.:\n $0 /storage/music/rock /storage/music/rock_links/\n\n"
  echo -e "Let's have 3 files:\n    /storage/music/rock/rock1\n    /storage/music/rock/rock2\n    /storage/music/rock/metal\n"
  echo -e "then inside /storage/music/rock_links/ you will have following files:\n"
  echo -e "    /storage/music/rock_links/RO/rock1\n    /storage/music/rock_links/RO/rock2\n    /storage/music/rock_links/ME/metal\n"
