Like I've said before, at least 1 well-respected, senior engineering person
(whose code likely is running on a good proportion of Linux machines) and who
was involved at a high-level with the open-sourcing of Solaris has
philosophical objections to dual-licensing - nowt to do with Linux. Also, a good
few Sun engineering folk have BSD backgrounds, and the BSD folk have not
always had good experience with how dual-licensing worked out for them with
BSD/GPL code that was part-maintained by Linux.
It's pretty clear even from external information on the net that the OpenSolaris
licensing decision had *several* dimensions to it. Only one, at best, was about
Anyway, this may well all be irrelevant now as it seems someone went and
