Well, for one thing, using
Options +foo (or -foo)
will explicitly override other options that are already set in the httpd config file - this will probably break cgi scripts. FollowSymLinks is already enabled in our config anyway.
I could be wrong, but my recollection is that, at least with our setup, you can’t execute a script that’s a symlink. You might be able to symlink a directory with scripts in it, or you could use a hard link.
