Typing out all the bootscripts in chapter 7 can be a long, tedious process, not to mention very error-prone.
To save some time, the bootscripts can be downloaded from http://ftp.linuxfromscratch.org/lfs-bootscripts/lfs-bootscripts-3.0.tar.bz2 or ftp://ftp.linuxfromscratch.org/lfs-bootscripts/lfs-bootscripts-3.0.tar.bz2 .
