I can comment as an ex-Sun employee who worked in this area.

This sounds like a release of the Janus technology tailored to run only in a Solaris Container, especially as its targetted as an OpenSolaris release of the technology.

The quick answer is yes. Red Hat's market share and the availablility of "Red Hat" applications means thats the way to sell the technology to customers.

I'm afraid although the LSB does good work and there are certified distributions  the question people ask is where are the LSB certified applications?

>From an engineering perspective to be able to be binary compatible with "Red Hat" to run "Red Hat" applications is differcult to ascert. All that could be claimed is that the solution is designed to be compatible. During my time and given my work in the POSIX/UNIX standards area I championed the use of LSB complience for the Janus technology due to the more measurable nature. Through running the testsuites and studying the specification although some issues remained Janus was quite close.

It will be interesting to see when the technology is released via OpenSolaris how the technology has developed.
