FSFS. My understanding is that the 1.4.2 (reported by running "svn
--version" on the server) is what ships with CentOS 5.5, and that it is
"backported" so that it includes recent updates, bugfixes, etc. I'm not
sure how to check what repo format is on the server, though. We have not
yet tried 1.5.7 or 1.6.16 server.

Thanks,
