I read the berkeley db argument as, "The filesystem is responsible for
authentication and enforcing access controls for local repositories". The
initial file system implementation, built on Berkeley DB, seems to be a
'permissions-free' file system. As you point out, implementing the
filesystem on top of a "real" DB would enforce whatever
authentication/access control mechanisms the DB enforced. I'm still
hoping for a plain-text unixy filesystem implementation at some point;
this impl would extends unix authentication/etc to SVN.
I just hope that SVN's filesystem interface includes an errno for
'permission denied' and that SVN will do a sensible thing if/when this
error is encountered.
