Only about a year and a half too late, I've coded a small shell script which is an initial (untested as yet) version of the Multi-Install Tool for Unix. The script may be found on the G3 dev wiki at http://dev.gibberlings3.net/index.php/Mult...ol/Unix_Version
(note that you will need to be registered at these forums in order to view this page). To use the multi-install tool, simply drop the code displayed there into a text file - eg, mit.sh , and making sure the executable permission is set, use as follows from a terminal:
./mit.sh current_install new_location
Please use this forum for support issues and general praise, and the talk page
for technical concerns (eg, bugs). Feel free to modify the code on the wiki page as you like, but please remember to explain the rationale behind your change in the Edit summary, and discuss non-trivial changes on the talk page first.
