The practical significance of LFS is not to compile mechanically. In fact, according to the document description, a simple release version can be generated by clicking the keyboard, which is not the purpose of the LFS that has existed for 13 years.
The significance of LFS is to let users know the function of compilation parameters, the function of patches and the working process of scripts attached to LFS, so as to achieve the purpose of making and perfecting the distribution independently from LFS.
Because LFS provides a general Linux distribution production process, LFS cannot guarantee that the final product meets the personal taste of the producer, nor can it guarantee the quality.
