Ah, thanks for the tip. It isn't inherit acls = true, as I already had that, and the behaviour is desirable for me. What makes the difference is force unknown acl user = true. But I don't really understand how can I make it work. Looks to me I have to somehow make mapping from fruit SIDs to unix gids? Any hints on what I'm missing?

I was trying to replicate how this behaves on truenas, but it may be more than a missing vfs. In fact they use some custom-made modules[1] specifically for that purpose. Maybe with the advent of TrueNAS Scale and it's usage of ZOL, they'll submit some stuff upstream
