上一篇说到，安装完10.10 DP2之后，在显示每个分区的磁盘工具中,各个分区看着有些异样，这是因为它把原来的普通分区转化为了Core Storage了。
下面是我安装在普通Mac3 (disk1s5)分区之后，磁盘的内部情况。参考我前面的三篇blog(OSX: 逻辑卷管理系统Core Storage(1), OSX: 逻辑卷管理系统Core Storage(2)和OSX: 逻辑卷管理系统Core Storage(3))来看即能看懂。
下面是运行diskutil list的结果，原来disk1s5处的Apple_HFS Mac3的地方被Apple_CoreStorage 的取代了，多出了一个disk2的Apple_HFS X.10dp2(注：X.10dp2是我把Mac3改名的结果)：

预期：Core Storage在新版本中可能会担当重任，有可能会发布第一个正式版本，而磁盘工具应该也会支持对Core Storage的更多功能，比如改变分区大小，创建新分区等等。
让咱们翘首以盼，抑或拭目以待吧。
