参考：LFS7.10——准备Host系统

LFS7.10——构造临时Linux系统

本文正式开始构建LFS系统，后面所有命令的执行都是在root用户下完成的。

这时开始构建LFS前准备工作

更改$LFS/tools属主

chown -R root:root $LFS/tools

准备Virtual Kernel File Systems

mkdir -pv $LFS/{dev,proc,sys,run}

创建初始设备节点

mknod -m 600 $LFS/dev/console c 5 1
mknod -m 666 $LFS/dev/null c 1 3

挂载和激活 /dev

mount -v --bind /dev $LFS/dev

挂载Virtual Kernel File Systems

mount -vt devpts devpts $LFS/dev/pts -o gid=5,mode=620
mount -vt proc proc $LFS/proc
mount -vt sysfs sysfs $LFS/sys
mount -vt tmpfs tmpfs $LFS/run

进入 Chroot 环境

chroot "$LFS" /tools/bin/env -i \
HOME=/root \
TERM="$TERM" \
PS1='\u:\w\$ ' \
PATH=/bin:/usr/bin:/sbin:/usr/sbin:/tools/bin \
/tools/bin/bash --login +h

准备LFS文件系统里面二点目录结构

mkdir -pv /{bin,boot,etc/{opt,sysconfig},home,lib/firmware,mnt,opt}
mkdir -pv /{media/{floppy,cdrom},sbin,srv,var}
install -dv -m 0750 /root
install -dv -m 1777 /tmp /var/tmp
mkdir -pv /usr/{,local/}{bin,include,lib,sbin,src}
mkdir -pv /usr/{,local/}share/{color,dict,doc,info,locale,man}
mkdir -v /usr/{,local/}share/{misc,terminfo,zoneinfo}
mkdir -v /usr/libexec
mkdir -pv /usr/{,local/}share/man/man{1..8}
case $(uname -m) in
x86_64) ln -sv lib /lib64
ln -sv lib /usr/lib64
ln -sv lib /usr/local/lib64 ;;
esac
mkdir -v /var/{log,mail,spool}
ln -sv /run /var/run
ln -sv /run/lock /var/lock
mkdir -pv /var/{opt,cache,lib/{color,misc,locate},local}

创建必需的文件和符号链接

ln -sv /tools/bin/{bash,cat,echo,pwd,stty} /bin
ln -sv /tools/bin/perl /usr/bin
ln -sv /tools/lib/libgcc_s.so{,.1} /usr/lib
ln -sv /tools/lib/libstdc++.so{,.6} /usr/lib
sed 's/tools/usr/' /tools/lib/libstdc++.la > /usr/lib/libstdc++.la
ln -sv bash /bin/sh

ln -sv /proc/self/mounts /etc/mtab

cat > /etc/passwd << "EOF"

exec /tools/bin/bash --login +h

初始化一下日志文件并加上合适的权限

touch /var/log/{btmp,lastlog,faillog,wtmp}
chgrp -v utmp /var/log/lastlog
chmod -v 664 /var/log/lastlog
chmod -v 600 /var/log/btmp
