I think you mean the setgid bit (so that all files in the subdirectory will
have group="foo"), and that should work on ZFS as well. Another option
might be to use ACLs to grant access to the "foo" group outside of the
standard unix mode system:
setfacl -m group:foo:rwx:df:allow /path
That will grant the "foo" group read/write/execute access on all files under
"/path" , regardless of the regular owner/group/umask settings. Also, make
sure that the zfs aclmode and aclinherit properities on the filessytem are
set to something other than "discard".
