Using fs-type would break backwards compatibility with BDB repositories
created by svnadmin 1.0.x (or earlier) that have never been dump/load-ed.

Now, since hot-backup.py was in tools/ in 1.0, it's formally covered by
the same backwards compatibility promise as everything else.

However, I don't think there are many people who use a repository
created by 1.0 that has never been dump/load-ed by any later version of
svnadmin; that is, I think few if any people would be affected by
breaking compatibility in this specific case. (And those who *would* be
affected would receive an error message, as opposed to silent misbehaviour.)

So, how about we (a) make the patch use fs-type, (b) issue an erratum¹
stating the breakage and providing the workaround?

Alternatively, we could just find some file that's guaranteed to exist
in all 1.0 BDB repositories and use that file if fs-type is missing.
