I don't need convincing of the merits to running a newer subversion.
It's a production system and we're viced by stability and contractual
guarantees. If I were on my own it'd already be the latest version
The Sun HG repository is so sun can publish their own patches in a way
so we can track and pull their changes. It's not meant to be an
alternative method of tracking any of the main development trees.
However, they will have to figure out how to track from SVN. Perhaps
they have a working method you could steal?
