劳驾,4.4BSD-based OS目前我就知道这FreeBSD、NetBSD、OpenBSD三个。。。        DragonFlyBSD和CloseBSD是来自FreeBSD。。。

好吧。。。要耍赖或者固执,我可以认输,我问几个问题:你认为UNIX-like是UNIX吗?你觉得GNU/Linux是UNIX吗?你认为无论性质如何只要有UNIX的设计理念那就是UNIX吗?而根本不用估计软件本身的性质?请正面回答。

丫。。。都把官方给的证据放在上面了,你拿出些什么证明给我看?还是你一厢情愿。。。哼

再说一遍,考虑问题是多方面的,你无法抛开一个软件的性质而单单从技术层面去定义。注册了The Open Group的UNIX商标的就是UNIX,否则符合POSIX设计标准的就是UNIX-like!

BSD UNIX确实是UNIX,这点我是承认的,但是这段历史你可以阅读一下《FreeBSD Handbook》就知道了,三大BSD早就不是当初那个BSD UNIX了

http://www.openbsd.org
The OpenBSD project produces a FREE, multi-platform 4.4BSD-based UNIX-like operating system. Our efforts emphasize portability, standardization, correctness, proactive security and integrated cryptography. OpenBSD supports binary emulation of most programs from SVR4 (Solaris), FreeBSD, Linux, BSD/OS, SunOS and HP-UX.

http://www.netbsd.org
NetBSD is a free, secure, and highly portable UNIX-like Open Source operating system available for many platforms, from 64-bit AlphaServers and desktop systemsto handheld and embedded devices. Its clean design and advanced features make it excellent in both production and research environments, and it is user-supported with complete source. Many applications are easily available through The NetBSD Packages Collection.
FreeBSD项目官方站点首页我没看到FreeBSD到底是UNIX还是UNIX-like,但是可以搜索

http://www.freebsd.org/docproj/docproj.html
In addition, FreeBSD will be the first exposure to a Unix-like operating system for many of its users, so the availability of high quality, accurate documentation is paramount.

http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/users-groups.html
A group is simply a list of users. Groups are identified by their group name and GID (Group ID). In FreeBSD (and most other UNIX like systems), the two factors the kernel uses to decide whether a process is allowed to do something is its user ID and list of groups it belongs to. Unlike a user ID, a process has a list of groups associated with it. You may hear some things refer to the ``group ID'' of a user or process; most of the time, this just means the first group in the list.

http://www.freebsd.org/doc/en_US.ISO8859-1/articles/explaining-bsd/x117.html
So what is really the difference between, say, Debian Linux and FreeBSD? For the average user, the difference is surprisingly small: Both are UNIX like operating systems. Both are developed by non-commercial projects (this does not apply to many other Linux distributions, of course). In the following section, we will look at BSD and compare it to Linux. The description applies most closely to FreeBSD, which accounts for an estimated 80% of the BSD installations, but the differences from NetBSD and OpenBSD are small.

要是連3個BSD都已經變成了unix-like, 那麽那些商業(sun ibm and so on)的系統豈不更是unix-like了? unix豈不是消失了

solaris、aix、hp-ux、还有sco unix等现在都是基于unix system v的。。。由于bsd unix中含有不到10%的unix system v的版权代码,影响了很多unix厂商,使他们不得不从bsd unix转向unix System v,以避免法律问题,以至于当今大多数商业unix版本都是基于unix system v的。

发现大字体在win下的效果不是很好,一样破碎变形,打开AA还行

xft灵活!能实现粗体的话就完美了。。。
我都不知道怎么给windows的字体引擎打开aa

跑题了,拉回来 :mrgreen:
freebsd可以到 ftp://ftp.freebsdchina.org/pub/FreeBSD/ISO-IMAGES-i386/下载
solaris可以注册后到官方网站免费下载,包括处在测试阶段的10 http://wwws.sun.com/software/solaris/index.html or http://wwws.sun.com/software/download/allproducts.html#S
