I don't want to pour water on your parade, but BLFS-8.4 is now so old (in LFS/BLFS terms) that many security vulnerabilities have come to light and installing it now cannot be recommended. Even with 10.0 there are a continuous stream of security fixes which need packages to be updated. But the real problems are in configuring the system for different hardware. In particular, different disk controllers but also different wifi or ethernet drivers. That is why commercial distros use modules for as much of the kernel as possible, and therefore provide an initrd from which the modules can be loaded. For modern laptops you probably need firmware for the wifi (I'm assuming that the hardware _is_ supported by the upstream kernel, distros may carry their own patches) and perhaps firmware for video, bluetooth, maybe other things. Distros also use various approaches for identifying the root filesystem (typically UUID) and updating (in their installers) the fstab. Alternatively, "Live" isos (typically, on sticks) need to have an area where data can be updated when the system is running. That is way beyond LFS (initrds are covered in BLFS) and most of the people here know nothing about that. > I had read somewhere that MacOS X was based on LFS 6.1. Not true. It is based on Darwin, which is based on "real" unix.
