UAE - written for Linux?

[johnklos]

UAE started on (free) Unix, not GNU/Linux.

I stand corrected. While it was developed ON a GNU/Linux system, it targeted (free) Unix systems, as one of the projects stated goals was portability.

In other words, it's not a GNU/Linux specific project. And it could never be a Linux specific project unless someone wanted to compile it into the kernel. After all, Linux isn't an operating system.

What's a "free Unix system"? Can you name any examples? You don't mean "free" as in "free beer", do you?

(free) Unix means Unix, generally (irrespective of trademark), and free Unix such as GNU/Linux and the BSDs.

While there are GNU/Linux (the OS) and Linux (the kernel) specific APIs, many open source projects are incorrectly associated with GNU/Linux. For example, KDE is not GNU/Linux nor Linux specific, yet people, especially so-called tech journalists, can't seem to get that it's just an open source project which happens to run on GNU/Linux as well as other (free)Unix systems.
