Wget

まず最初に、wgetをインストールする。wgetを最初にインストールしておかないと、chroot環境からパッケージがダウンロードできない。今回インストールするのはSSLに非対応なので、SSLをインストール後からコンパイルし直す。

chroot環境の外で

sudo mkdir /mnt/lfs/root/src-blfs &&
wget http://ftp.gnu.org/gnu/wget/wget-1.14.tar.xz &&
sudo mv wget-1.14.tar.xz /mnt/lfs/root/src-blfs

chroot環境で

cd /root/src-blfs &&
tar Jxf wget-1.14.tar.xz &&
cd wget-1.14 &&
./configure --prefix=/usr \
            --sysconfdir=/etc \
            --without-ssl &&
make &&
make check &&
make install &&
cd ../ &&
rm -rf wget-1.14

BLFS bootscriptsのダウンロード

後から何回も使用するので先にダウンロードしておく。

cd /root/src-blfs &&
wget http://www.linuxfromscratch.org/blfs/downloads/svn/blfs-bootscripts-20130324.tar.bz2

BLFSの環境設定
