[Live-demo] 5.0 Beta 4 Status - Space

[Alex Mandel]

We did change from checkout to the method that doesn't create .svn
folders but then found it making it harder for us to fix some things
that just required svn up. I suppose in the build_iso.sh script we can
easily add a line or two to remove the folder or just the .svn folders
inside of it.

That sounds like a good idea since space really isn't a concern on the
vm we give out and we do want people to see how we did the install and
setup. It's actually a good way to learn how to do the setup, I use the
postgis script all the time to help me do installs.

Anyone want to take charge and recursively delete .svn folders out of
the checkout in the build_iso script (could be a separate subscript for
modularity).

Thanks,
Alex
