[81fd230] | 10 | <para>The steps in this section are optional, but if the LFS partition
|
---|
| 11 | is rather small, it is beneficial to learn that unnecessary items can
|
---|
| 12 | be removed. The executables and libraries built so far contain about
|
---|
| 13 | 130 MB of unneeded debugging symbols. Remove those symbols
|
