开源UNIX：FreeBSD 6.3-RC1发布

　　FreeBSD是一份UNIX操作系统，它面向i386、IA-64、PC-98、Alpha/AXP及UltraSPARC平台。它基于加州伯克利大学的4.4 BSD-Lite发布，并带有一些4.4 BSD-Lite2增强。

它还非直接地基于William Jolitz的port，这源于加州伯克利大学i386化的“Net/2”也即“386BSD”，尽管386BSD中只有非常少的代码遗留下来。

 FreeBSD被遍布全世界的公司、Internet服务提供商、研究人员、计算机专家、学生，以及家庭用户用于他们的工作、教学和娱乐之中。

　　Ken Smith has announced the first release candidate for FreeBSD6.3: "The first of the release candidate builds for FreeBSD 6.3 is now available. There is one more release candidate planned, which will be followed by the release unless a major show-stopper issue crops up during testing. The release branch has been created so if you plan to use cvsup to update an already installed machine you should use the RELENG_6_3 branch. Or you can give FreeBSD Update a try, see the instructions here. The ports folks are getting very close to finishing up the release package builds for a couple of the architectures. I'm planning to fiddle a bit with figuring out the disc1 and disc2 package sets that we will be trying to provide as part of the final release." Here is the brief release announcement.
