Well, I've found the answer to my previous post about how to create multiple GVM installations on the NIT--I just needed to try using the forum tools a bit more extensively.
I found burmashave's instructions (Thanks, burmashave!) here:

What I don't yet understand is where all the code is supposed to go. As a newbie, I presume I should input this all into Terminal, but I also wonder about how to create Scripts (for repeated commands). I haven't found out the instructions for doing this in the Maemo Wiki.
