Derek, selinux is not present and is not your problem.
I tested adding a shapefile using GeoServer 2.5.2, then moving the directory away, and substituting a symlink. The shapefile continued to work. As far as I can tell, you are doing everything right. The user interface is a bit broken in my browser, but that is a separate issue. It was equally broken with and without the symlink. I had to manually edit the url. Kind regards, Ben.
