--- Comment #2 from Kyle Evans <kevans@freebsd.org> ---
You could workaround this initial problem by making your exec.poststart an
exec.created, but you would need D28952 on top of that for jail creation to
succeed as the next step won't be able to attach without widening its mask
pre-attach. exec.created is debatably the more appropriate place for
resource-control type stuff anyways, though it doesn't matter much at all f=
or
cpuset.

We're still discussing in that review and elsewhere whether this can be fix=
ed
quickly in a low-impact way besides reverting the original change; we should
arrive at something before -rc1.
