In my experience, the svnsync properties in r0 don't affect operation
of the repository in any way. The trouble is to keep people from
comitting to the DR repo while the master still exists. When disaster
strikes, just let the users access the DR repo, delete the svnsync
properties when you have time and set up a new DR server.

I migrated quite a few peositories that way - set up a sync repository,
disable the old one and have users start using the new one.

I know there are SVN masters out there - please correct me if I'm wrong! :-)
