I remember playing with Gobo several years back. Although renaming system directories makes it a bit more approachable to newcomers, it also makes it less language independent and less recognizable to the users who typically need to use it (sys admins and such).

However, the general idea of installing things in a self-contained directory was fantastic, and I'm happy to see another operating system trying something similar. I used to use PC-BSD regularly, whose package manager also does this:
