Added support for ZFS Storage Plugin
example of storage.cfg
zfs: omnios
blocksize 8k
target iqn.2010-09.org.openindiana:target1
pool pool1
iscsiprovider comstar
portal 192.168.0.1
sudo 1 (optionnal)
content images
note for fast ssh login:
on solaris host :
/etc/ssh/sshd_config
LookupClientHostnames no
VerifyReverseMapping no
GSSAPIAuthentication no
note for nexenta:
rm /root/.bash_profile
to avoid to go in nmc console by default
