Got it.
Question. I'm considering open source solution and I haven't followed
Solaris in full. I think Solaris is now open source, right? Are these
features shipped with the OS, or do they come separately? If separately, are
they open source?
Also, I can run Solaris on a x86 ISA, right?
thanks,
Daniel.
