So I guess the above one is the more 'transparent' one with respect to 
the future, when NFSv4 gets mature and its way as matured into the kernel?

I tried the above and it works. But it seems, that only UFS2 filesystems 
can be mounted by the client. When trying mounting a filesystem residing 
on ZFS, it fails. Mounting works, but when try to access or doing a 
simple 'ls', I get

ls: /backup: Permission denied


On server side, /etc/exports looks like

--
V4:     /       -sec=sys:krb5   #IPv4#

/backup      #IPv4#
--

Is there still an issue with ZFS?
