The repository format and the filesystem format are two different things. The
repository format lives at $REPOS/format, while the filesystem format is in
REPOS/db/format, and was added in 1.4. In the foreseeable future, only the
filesystem format will change, and bdb and fsfs formats can change independent
of each other.

These are filesystem formats, and the latter specifies a sharded layout with
1000 revs per shard. You can read more about FSFS filesystem formats here:

That document is a little out-of-date, but it is correct in that the repository
format in version 1.4 and higher is 5. If you look in $REPOS/format, you'll see

Looks like you're seeing what you ought to; no cause for concern. Does the
repository *work* like it should?
