前阵子我们谈得很高兴，最近 FreeBSD 总部 (mailing-lists) 刚好也谈到这件事...

-> 11. FreeBSD v.s. Linux v.s. Solaris
诚如 grog 所说，Linux 太红了，不用担心没人用，就像 sendmail 一样 :-)
woju 将尽可能的用各种「烂招」，让多一点的人知道有 FreeBSD & qmail 这样的
东西，并愿意试试，甚至全心投入...
对 FreeBSD 有进一步兴趣的朋友，欢迎逛逛:

The background of this discussion is a comparison between FreeBSD and
Linux that I wrote for "The Complete FreeBSD". Here goes; there's
more from David Kelly after it.
FreeBSD and Linux
Linux is a clone of UNIX written by Linus Torvalds, a student in Helsinki,
Finland. At the time, the BSD sources were not freely available, and so Linus
wrote his own version of UNIX.
Linux is a superb example of how a few dedicated, clever people can produce an
operating system that is better than well-known commercial systems developed by
a large number of trained software engineers. It is better even than a number
of commercial UNIX systems.
Obviously, I don't think Linux is as good as FreeBSD, or I wouldn't be writing
this book, but the differences between FreeBSD and Linux are more a matter of
philosophy rather than of concept. Here are a few contrasts:
Table 1-1. Differences between FreeBSD and Linux
FreeBSD is a direct descendent of the Linux is a clone and never contained

and easy to install. If you switch from one distribution
of Linux to another, you'll have to
learn a new set of installation

In summary, Linux is also a very good operating system. For many, it's better
than FreeBSD. It's a pity that so many people on both sides are prepared to
flame each other. There are signs that both sides are learning to appreciate
each other, and a number of people are now running both systems.
So much to that; I welcome comments or corrections. Now to David's
message.
