He's not the only one. I've been here for a long, long while.

Bzzt. SFU is no longer a seperate product. It's part of Windows now, in Windows Server 2003 R2 and above - which includes Vista, Windows Server 2008, and Windows 7.

It's called the Subsystem for UNIX-based Applications (SUA). Relevant TechNet link: http://technet.microsoft.com/en-us/library/cc786798(WS.10).aspx

Here's a good Wikipedia article on the product, showing the history from Interix, to SFU, to SUA: http://en.wikipedia.org/wiki/Interix

There's even a Debian port for it: http://debian-interix.net/

The only problem there is that "7" is a marketing term only. The kernel version is 6.1. Here it is from a CMD window, pasted right into Slashdot:

Microsoft Windows [Version 6.1.7000]

I, myself, can't stand the "7" moniker. It's misleading, and no better than the year-themed marketing names. Well, okay. Marginally.

Why can't we just call it what it is? 6.1, for chrissakes.
