Huh? Why?

The revision number does nothing more than count the number of
modifications to the repository. If it bothers you then ignore it. It
hardly seems worth the overhead (in effort and space) of maintaining
thousands of repositories just so that you can keep your revision
numbers "reasonable". If you want to keep track of particular
versions of articles, consider using tags (see the subversion book).

Since we've got hundreds of thousands of articles, I'm concerned I
might hit a maximum number of subdirectories if I store all
repositories under one directory.

We'll be using either ReiserFS or Reiser4. Anybody here know the max
subdir limits of these filesystems ?

How about for JFS, XFS, or EXT3 ?

EXT3 is the only file system where I'd worry about performance of
very large directories. (but see above).

p.s. You wrote yesterday asking what to do about a disk that's
getting full. Creating thousands of repositories is a good way to
make sure the disk fills up even faster. (After all, there's a
certain fixed cost beyond the actual contents for every repository).
