The script is easy and lazy solution, but he it works. There exist more universal script: "pkgscan.sh" - it allows you to optify any installed packages whenever custom or nokia ones (be careful while optifing nokia stuff as the script uses no blacklist so wrong decision about some nokia ones may brick your device) - of course you choose which ones to process - and optifies packages file by file which seems more safe than optifing whole directory at once, as directory symlinks makes problem when using ".." as since moving and symlinking another directory becomes "one level up". The script also supports partially working "undo" ability, which you may want to use if you update the packages (since not doing it may leave unneccesary files in /opt/relocated but its not a big problem because it's out of rootfs), or if you know you did a mistake (do it better before you reboot as booting even a partially bricked device without reflash is really hard however possible eg. if you have multiboot install and booting something not maemo works) so doing a mistake is not yet bricking the device.
