since OpenSolaris is more or less abandoned by Oracle, is there a nice alternative that implements the unique features of OSOL? ZFS is one thing, but I liked the image creation system, that let you create images of a master system and then distribute it quickly to other computers. This was an effort to simplify creation of clusters.
According to the Wikipedia page of OSOL, there's Illumos, which is a fork of OSOL, with all closed source parts replaced by open source parts. Illumos is in active development.
But is Illumos an alternative to OSOL, with all it's features? Is anyone using it and could tell us his or hers experiences?
