oh no..
Seems I do need NFS kernel options for zfs.
If I remove NFS, I get:

Loading /boot/defaults/loader.conf 
/boot/kernel/kernel text=0x966fb0 data=0x96164+0x2161ac syms=[0x8+0x80718+0x8+0x76ed5]
/boot/kernel/zfs.ko text=0x22e4f8 data=0x9060+0x16de8 syms=[0x8+0x16c20+0x8+0x11725]
loading required module 'opensolaris'
/boot/kernel/opensolaris.ko text=0x3338 data=0x510+0x2030 syms=[0x8+0xcd8+0x8+0x872]
loading required module 'krpc'

KLD zfs.ko: depends on krpc - not available or version mismatch
kldload: can't load zfs: No such file or directory
/etc/rc: WARNING: Unable to load kernel module zfs

I guess now that zfs needs module acl_nfs4,
the latter needs NFS, right?

Or can module krpc be loaded instead?

Anyway, I put new NFS options in the kernel,
and now zfs works ok.

Thanks
