I'm sure, but note 8-STABLE != 8.2.0-RELEASE. I'm talking about the
stable/8 branch, which will become 8.3.0-RELEASE.
We don't have a package for this yet, maybe we should put it in experimental?

It will have both kfreebsd 8.3 and kfreebsd 9.0 (unless they're
delayed and miss the freeze). There's no decision made on which one
should be default.
As for userland, it's most likely either 8.3 or 9.0. It's almost
impossible for us to support both.
If most interesting features (e.g. ZFS v28) have been backported to
8.3, that's a point in favour of using 8.3 kernel as default and/or
staying in 8.3 for userland.
A clear advantage of upgrading zfsutils to 8-STABLE before going for
9-STABLE is that we don't discard possibilities. If later we decide
we want zfsutils 9.0 in Wheezy, we can upgrade further.
Also it is easier to detect and fix bugs if we upgrade one step at a time.

Please talk to Guillem.

It'd be interesting to know if 8-STABLE version has the same ABI problems.
