拥有UNIX商标和代码就能称为UNIX？AT&T的1127早就解散了，SCO也被拆散而且SCO代码中也被加入很多来自unix-like的代码，上个世纪末电信也升级了服务器，淘汰掉了SCO，现在UNIX~没有人能说清楚UNIX是哪个版本了。

lilo？还有哪个发行版在用吗

Makes a lot of sense to me. Why go on yelling "fire, fire!" when there isn't even any smoke? People on the Ubuntu forums will always warn you not to work unnecessarily in root because of the inherent dangers involved in doing so. Well, like you say-- why isn't this puppy forum filled with cries of anguish about what happened all these years with thousands of people working continuously in root?

The main danger for the user running as root is the user him/herself. You are far more likely to screw up your own system than have someone hack you and screw up your system. Also, as has been said here, most non-root distros give you sudo. If your non-root account gets compromised, the hacker then types sudo+evil_command and does whatever s/he wants.

The use of sudo only makes the user think twice before doing something stupid, it does nothing to stop the hacker.

As an aside, is anyone else noticing the large amount of interest in the security of running as root?

有段时间没关注了，试用了一下新版本，图标很美观，程序安装很人性化（指浏览器、QQ），支持1440X900，网络自动连接上了（免配置），文件管理器用不习惯，希望能出个xfce版的。另外弱弱的问一下，第一张图片里桌面上的几个是什么东东？
