Yes, I already catched it; see below.

Anyway, it does not work, alas:

marck at beaver:~# zfs set sharenfs="ro,alldirs,network=195.54.192.0/26,network=192.168.39.0/24" bv/FreeBSD
marck at beaver:~# tail /var/log/daemon 
Sep  8 13:22:11 <daemon.err> beaver mountd[25992]: network/host conflict
Sep  8 13:22:11 <daemon.err> beaver mountd[25992]: bad exports list line /FreeBSD       -ro -alldirs -network
marck at beaver:~# cat /etc/zfs/exports 
# !!! DO NOT EDIT THIS FILE MANUALLY !!!

/FreeBSD        -ro -alldirs -network=195.54.192.0/26 -network=192.168.39.0/24 


What I' m trying to express is that there would be need to export the same file 
system to different address blocks *with different options* - -such as rw/ro, 
and/or maproot/mapall.

I'm starting to think we should either mimic such functionality from 
OpenSolaris or invent it.

Thank you for cooperation!

Sincerely,
