说明：  Linux入门是很简单的，问题是你是否有耐心，是否爱折腾，是否不排斥重装一类的大修。 没折腾可以说是学不好Linux的，鸟哥说过，要真正了解Linux的分区机制，对LVM使用相当熟练， 没有20次以上的Linux装机经验是积累不起来的，所以一定不要怕折腾。
(APUE, UNIX environment advanced programming, Linux entry is very simple, the question is whether you have patience, whether love toss, whether or not to reject the heavy repair. Don t toss about can be said is cannot learn Linux, Costa Rica said to truly understand the Linux partition mechanism, of LVM uses quite skilled, no more than 20 times the Linux installed experience is not accumulated up, so don t be afraid to do sth over and over again.)
