Greg,
We do a "hack", which is not a pretty one, populating /sys with .htaccess files. This is really needed only by shared hosters, where one of the end users on the server, could be a hacker and could create symlinks that would later be followed by apache to read privileged information. A better fix would be fixing the apache. Yet, surprisingly enough -- we control kernel on those servers -- but we don't control apache. So -- we tried to secure things for our customers in this particular way. Most likely we will through it out anyway.
