====== Default root's shell ======

Change root shell in /etc/passwd can be dangerous sometimes, Sun even recommand
to never change it. But sh is annoying, prefer something like :

<code>
# echo "zsh" > ~/.profile
</code>


====== Allow ssh authentication key based ======

__/etc/ssh/sshd_config__
<code>
PubKeyAuthentication yes
AuthorizedKeysFile %h/.ssh/authorized_keys
</code>

<code>
# svcadm refresh ssh
</code>
