I'd really, really like to encourage people wanting to do things like Scibuntu to contact the Ubuntu science development team for Universe (MOTU Science). PM me if you want more info. We will most likely be working on official ways to easily install science package groups for Fesity. The Scibuntu script does a couple of odd things like use -q with apt-get so they don't see that there is a typo for treeviewx and installing acroread from Adobe rather then the Ubuntu repositories.
In general, creating a script to install packages is handy for personal use, but not so great at all for widespread distribution. We should avoid duplicating effort and doing things through the development community has the added benefit of making things available to all Ubuntu users. There are already a ton of Ubuntu derivatives, maybe we shouldn't be confusing users by creating a whole new name for an apt-get script.
