Emerald Boa is available for CentOS 6.3 (Rocks 6.1). The Rocks-supplied OS rolls have all updates applied as of November 27, 2012. New features: host-based SSH authentication is now the default, this eliminates the requirement the users have password-less SSH keys and/or mounted home area on remote nodes; two-factor SSH authentication using Google Authenticator Apps for Android and iPhone is supported for all users; New ZFS Linux roll to support the ZFS file system via the ZFS on Linux; new kernel roll to more easily support vanilla Linux kernels."
