So, now I know how another server does it. This has changed. I wrote this up here: http://cryptonector.com/2011/11/zfs-aclchmod-interactions-in-solaris-11/ IIRC all ACEs for anything other than OWNER@ (or a user of the same name/ID) contribute to the group bits of the mode, the EVERYONE@ entry contributes to the world bits of the mode, and the OWNER@ and/or user ACEs for the owner name/ID contribute to the owner bits of the mode. The new scheme is really much simpler and more natural than everything else tried before.
