@Anniiii No. In lots of these cases I rely on others to tell me about them as I certainly don't know details about 100 operating systems myself. If OmniOS is "just" as distro flavor of Illumos, then I think it should not count as its own OS.

thank you for your titanic work.
I wish more software was developed this way.

That would make for a very interesting keynote presentation on #FOSDEM

@Anniiii someone now pointed out another one that was missing. So, still at 100 even without OmniOS! =)
