We saw this coming.
As of 23 August 2010, the OpenSolaris Governing Board (OGB) has stepped down; Ben Rockwood posted the resolution on his blog.
Oracle’s previous email to staff shows that Oracle has no interest in keeping OpenSolaris going, and now there is no one minding the store.
The next step lies with Illumos, the new torch-bearer for open source Solaris. Nexenta, the commercial UNIX based on OpenSolaris and a GNU userland will probably be the first to use Illumos (the project has close ties to Nexenta) – and Belenix may be next, although Belenix development seems to be quite slow (there is no corporate sponsorship and the community seems to be small). Belenix has the tougher problem, as they use a Solaris-based userland.
