Sure, I think the confusion arises from the fact that Windows' boot.ini hands the boot off to Linux. That line referring to Linux can be worded any way at all; it could say "Suzy's Linux", and that will call NTLDR (the Windows bootloader) to bring up, indeed, Suzy's Linux.
It is really a chain, though. Boot.ini, by any wording at all, is actually asking NTLDR to call up either LILO or Grub, and one of them is actually starting Linux. YOU know that. But, as far as Suzy is concerned (assuming the config was done for her by somebody else) it looks for all the world as though Windows is calling up Linux. After all, her options on the screen are for Windows or Linux; she has pressed for Linux; and here it is.
(By the way, not only will the typical user never have heard of NTLDR or Boot.ini. The typical user will never have heard of a boot loader—Windows' or anybody else's. I worked with Firefoxes and K-Meleons for several years, and I learned that the average person doesn't know what a "browser" is. And why should he? He could be brilliant in his own field.)
IMO a huge lot of folk will go for Linux if they can play with it for a time without changing their Windows startup. In fact I think that is likely a bigger group than the people who are happy to trade right over. That's why it is good for Slackware or any distro to be friendly toward the Windows loader. It is the same with anything; you can think of all sorts of things you'd try "no-risk", but you'd hesitate trying otherwise. If I said I had a better carburetor for your car, my own enthusiasm wouldn't convince you—even if I said I could trade them back, you'd likely say, "No, thanks." But what if I said I could install my carburetor without removing yours? (A Knoppix carburetor!
) So, even though your readers will know you're "right" about LILO, lots of them will prefer to keep NTLDR functioning just fine (for the time being). Let them do that, help them with it, and you'll see lots more people getting Slack, or any Linux distro. Haha! My carburetor analogy is pretty bad, but I'm sure you can think of a better one.
