As its name implies, LinuxFromScratch is different from "other distros" in that it is designed to teach
you how a Linux system is actually built ... from the ground up, using nothing but sources. As such, it does not automatically use "packages" like most other distributions do.
When you get a typical distribution, what you are getting is (for the most part) the binaries
that someone else,
namely the distributor, has pre-compiled for you. Installing the system is basically a process of installing the requisite packages, which are designed to automatically deal with issues such as putting things into the right place, checking for co-requisite and pre-requisite packages, and running any installation-scripts. Per contra,
LinuxFromScratch is specifically designed not
to do this "for you," but rather, to "show you how."
As you gain experience with Linux, you will probably start out with a different distro and move-to LFS at a later time. Starting out with LFS, right from the get-go, might be appropriate if you have plenty
of spare hair.
