    1313  <para>There are many reasons why somebody would want to read this book.
    14   The principal reason is to install a Linux system from the
    15   source code. A question many people raise is, <quote>why go through all
    16   the hassle of manually building a Linux system from scratch when you
    17   can just download and install an existing one?</quote> That is a good
    18   question and is the impetus for this section of the book.</para>

    20   <para>One important reason for LFS's existence is to help people learn
    21   how a Linux system works from the inside out. Building an LFS system
    22   helps demonstrate what makes Linux tick, and how things work together
    23   and depend on each other. One of the best things that this learning
    24   experience provides is the ability to customize Linux to your own

    27   <para>A key benefit of LFS is that it allows users to have more control
    28   over the system without relying on someone else's Linux implementation.
    29   With LFS, <emphasis>you</emphasis> are in the driver's seat and dictate
    30   every aspect of the system, such as the directory layout and bootscript
    31   setup. You also dictate where, why, and how programs are installed.</para>

    33   <para>Another benefit of LFS is the ability to create a very compact
    34   Linux system. When installing a regular distribution, one is often
    35   forced to include several programs which are probably never used. These
    36   programs waste disk space, or worse, CPU cycles. It is not
    37   difficult to build an LFS system of less than 100 megabytes (MB), which
    38   is substantially smaller than the majority of existing
    39   installations.  Does this still sound like a lot of space? A few of us
    40   have been working on creating a very small embedded LFS system. We
    41   successfully built a system that was specialized to run the Apache web
    42   server with approximately 8MB of disk space used. Further stripping
    43   could bring this down to 5 MB or less. Try that with a regular
    44   distribution! This is only one of the many benefits of designing your
    45   own Linux implementation.</para>

    57   <para>Another analogy that we can use is that of comparing LFS with a
    58   finished house. LFS provides the skeletal plan of a house, but it is up
    59   to you to build it. LFS maintains the freedom to adjust plans throughout
    60   the process, customizing it to the user's needs and preferences.</para>
