subversion: is already a working copy for a different url
Introducing version control to an existing project.
A project directory contains files which are common to all and also some which are specific per installation/host.
So I tried to keep them in different paths on the svn repository. This requires that I check out from different repository paths into the same directory. But svn does not allow this: 'x is already a working copy for a different url'
The logical thing would be to rearrange the directory structure of the project, however I would prefer not to tackle that task.
I am new to svn and have not yet discovered how svn takes care of this situation.
