Re: Hook script issue

As you figured out, you can't make any changes without a working copy,
and the hook scripts don't have access to the working copy.

However, what you may want to do is use svn:externals. With this
property, you don't store multiple copies of a file. Instead, the
copies are checked out when a user checks out the other directory. See
<http://svnbook.red-bean.com/en/1.0/ch07s02.html#svn-ch-7-sect-2.3.6>
and <http://svnbook.red-bean.com/en/1.0/ch07s03.html> for more
information.
