OpenSolaris 2008.05 has been released08 May 2008
It seems like Sun made a right choice hiring Ian Murdock. I installed OpenSolaris last night in a VMware Fusion instance, and it looks sweet: bash is the default shell, seperate /root home directory, live cd which acts as a install cd, ZFS, Xen, DTrace, Containers, a new package management system IPS. Now if only Sun could do something about the lack of hardware support.
