Neither SVR3 nor 4.3BSD is capable of fully emulating the other's services. It happened that I needed a System V environment for applications and software development and had to use Berkeley-based systems, so I designed and produced an SVR2 emulation that can be added as a layer atop 4.2BSD or 4.3BSD. I don't know what Mt. Xinu's currently offering, but they started with my System V emulation as an add-on option for the 4.nBSD systems that they offer commercial support for. As Melinda said, there is a lot of bigotry out there. Mostly I think it stems from people being annoyed when faced with environments that don't offer all the facilities they've gotten accustomed to. As one who works primarily in a System V environment, I find "raw BSD" extremely annoying. Just as Rahul is accustomed to BSD and finds raw System V annoying. The best environment is probably one that offers the facilities of both, e.g. 4.3BSD+BRL SysV emulation, or SVR4, or several vendor offerings.
