Re: Running the 1.7.0 pre-releases on svn.apache.org

We have the option of running alphas on the mirror (harmonia/svn.eu)
while leaving svn-master(eris) on 1.6.x.

The idea being that if eris runs a stable release it would require two
bugs, rather than one, to corrupt both mirrors of a given repository.

Let's make this clear: the risk is corrupting the versioned filesystem.
(The fsfs, not the zfs.)
