Even that wiki says its a type of emulator
just not the kind most people think of.
To argue some of you points:
- Pretty much every OS has an IDE
- Not every distro has Package managment and automatic updates, other OSs do have package managment and automatic updates (ie. FreeBSD), windows has automatic updates but each aplication has to support it themeselves
- Linux is not the only OSS OS
- Again Linux is not the only OS that can do clustering, even Windows can do it
- Stability is somewhat a YMMV subject. Some people have great stability with windows, some people don't. More people tend to find Linux more stable, but not all. Anyway, I'd say OpenBSD or NetBSD to be more stable than Linux
- Not sure what you mean about Client/Server framework. That has nothing to do with an OS.
- same as above about Libraries database
- I'll give you this one. Generally Linux has the best performance, YMMV again though. A monolithic kernel isn't a plus imo. Hybrid's the way to go these days. Also, Linux isn't the only OS that allows for tweaking and optimization.
- Virtual Machines and hardware virtualization has nothing to do with an OS. Linux does tend to have more than other OSs but that only because its more popular.
- EVERY os has some kind of debugging utility. Linux doesn't even have the best one imo, dtrace. Well it does, but its incomplete last I checked.
- Not sure what you mean by security policy. If you mean something like PAM, that's in a TON of OSs
- Linux is fairly moodular, more than most. I'll give you this one, but I'd argue that NetBSD is more modular.
- I wouldn't say Linux has amazing documentation. Its fairly good, but does not compare to FreeBSD's documentation imo.
- X has no relation to Linux other than it runs on it. Xorg will run many different OSs. Hell, You can run gnome on Windows if you wanted to.
You seem to think the GNU userland is confined to Linux. It is not. The original goal of the GNU userland was to run on GNU Hurd (who knows when that will be finished), but the applications run on pretty much any *nix or *nix like (Linux) OS.
