IMHO, a base LFS install isn't very useful. LFS simply gets the system "up and running" (which is what it is intended to do). For me it was very educational, but the end product is not very useful for any type of environment. In order to get a really useful linux system, you need to complete *atleast* chapter 3 of BLFS and pieces of chapters 4, 5, 6 and 8. In my experience the entire (B)LFS process isn't difficult, so much as it is time consuming.
And if you want to know what BLFS is all about, read chapter 1 of BLFS.
