I think the question is not new but I only found an old talk for version
3.x, so I want to ask again:
Is there anything comparable to FreeBSD jails (now)?
I found sysjail but I am not sure, if it is working under 4.9 (maybe I
will try it in the next few days):

I haven't touched sysjail since 4.3 and nobody's sent patches to update
it since then (though some hot air's been blown around). The linked
tutorial is also wrong: it just copies around some ifdefs instead of
actually making sure nothing's changed between versions. Bad. Please
contact me off-list if you're SERIOUS about maintaining sysjail between
versions (no patches = don't bother). Of course, this won't change that
sysjail is breakable (and, note significantly, NOT part of OpenBSD proper).
