[2ca8941] | 13 | <para>As stated earlier, the goal of LFS is to build a complete and usable
|
---|
| 14 | foundation-level system. This includes all packages needed to replicate
|
---|
[c6d5b092] | 15 | itself while providing a relatively minimal base from which to customize
|
---|
[a26951e] | 16 | a more complete system based on the choices of the user. This does not
|
---|
| 17 | mean that LFS is the smallest system possible. Several important packages
|
---|
| 18 | are included that are not strictly required. The lists below document the
|
---|
| 19 | rationale for each package in the book.</para>
