/foot和SWAP都没有分,因为我觉得:只装一个Linux的话没必要分/foot,4G内存,没必要分SWAP 根据LFS的文档:http://www.linuxfromscratch.org/lfs/view/stable/chapter02/creatingpartition.html “A separate /usr partition is generally used if providing a server for a thin client or diskless workstation. It is normally not needed for LFS. A size of five gigabytes will handle most installations.” 为什么要单独分出来呢?
