Good idea. The conf directory for each user is completely different.

I have always thought that different checkouts work fine with update and
commit when starting at some top-level svn controlled directory and doing it
recursively. In fact it would be hard to believe it does not. Each directory
has its own .svn file, so it knows the repository path it points to.

The repositories themselves have no pointers to local directories but rather
the other way around. The local directories under svn control point to
repository paths.
Thanks for your suggestion of not having the 'conf' directory under svn in
the main repository. It will save me from having to delete the .svn
directory before checkout again.
