If the Etude code was free to look at even if not to use (since I don't know if it would be possible to open it entirely), or there was at least a complete description of what interfaces it made backwards-compatible (and a growing list of what had been tested on it), I think that could be discussed more comprehensively. But in one sense I'm not sure I'd want a back port (even if I thought it might actually happen), because it would take away excuses for upgrading. After all, properly written apps (as if typical in-house app developers bothered...) should just work on newer OS releases anyway. In most cases, LDOMs (or zones) would at least provide a very inexpensive (as a share of a whole system) place to host test/development "systems", already reducing the excuses for not migrating to current versions of Solaris. IMO, of course... -- This message was posted from opensolaris.org
