SUReLinux项目构建手册（内部文件，不要外传，参数说明见LFS官方文档）
第一章 准备系统
1.1准备工作
本文假定中途不会关机，推荐使用虚拟机挂起功能。
作者在VMWare Workstation 15.5下测试。（请不要使用virtualbox，virtualbox的CPU利用率较低，在支持超线程的CPU上面甚至低于hyper-v。qemu存在桥接网卡的问题，方案自行检索。hyper-v, xen未测试）
内存推荐4G，最少2G, swap最少4G。硬盘80G（完整版内核需要15G以上空间编译，所以必须要这么大硬盘，使用虚拟机的话，直接创建80G以及以上硬盘即可），处理器能好点用好点的，只要是64位处理器就行。
LFS系统宿主机要求（按照LFS要求筛选之后）：OpenSUSE(leap, tumbleweeded均可，推荐)
mageia(推荐）
ubuntu/debian/kali（debian与kali请用su - root代替su，并请运行sudo dpkg-reconfigure bash，将默认shell从dash切为bash)
archlinux/manjaro（archlinux vmware剪贴板异常，manjaro安装gtkmm gtkmm3后没问题）
gentoo/funtoo（vmware剪贴板异常），debian/kali（普通用户的su请改为su - root）
已知存在问题的不符合要求的：fedora/centos/rhel（yacc这边不一致，fedora可用opensuse的bison安装包代替），alpine(使用的是musl，不是glibc)，solus(多项不符合要求)，WSL（没有lsblk，无法chroot）。
另外请自行准备ocserv服务器/代理服务器，aria2c或者wget
使用如下代码检测是否安装全必要的软件
cat > version-check.sh << "EOF"
#!/bin/bash
# Simple script to list version numbers of critical development tools
export LC_ALL=C
bash --version | head -n1 | cut -d" " -f2-4
MYSH=$(readlink -f /bin/sh)
echo "/bin/sh -> $MYSH"
echo $MYSH | grep -q bash || echo "ERROR: /bin/sh does not point to bash"
unset MYSH

echo -n "Binutils: "; ld --version | head -n1 | cut -d" " -f3-
bison --version | head -n1

if [ -h /usr/bin/yacc ]; then
  echo "/usr/bin/yacc -> `readlink -f /usr/bin/yacc`";
elif [ -x /usr/bin/yacc ]; then
  echo yacc is `/usr/bin/yacc --version | head -n1`
else
  echo "yacc not found"
fi

bzip2 --version 2>&1 < /dev/null | head -n1 | cut -d" " -f1,6-
echo -n "Coreutils: "; chown --version | head -n1 | cut -d")" -f2
diff --version | head -n1
find --version | head -n1
gawk --version | head -n1
echo -n "pkg-config "; pkg-config --version
if [ -h /usr/bin/awk ]; then
  echo "/usr/bin/awk -> `readlink -f /usr/bin/awk`";
elif [ -x /usr/bin/awk ]; then
  echo awk is `/usr/bin/awk --version | head -n1`
else
  echo "awk not found"
fi

gcc --version | head -n1
g++ --version | head -n1
ldd --version | head -n1 | cut -d" " -f2-  # glibc version
grep --version | head -n1
gzip --version | head -n1
cat /proc/version
m4 --version | head -n1
make --version | head -n1
patch --version | head -n1
echo Perl `perl -V:version`
python3 --version
sed --version | head -n1
tar --version | head -n1
makeinfo --version | head -n1  # texinfo version
xz --version | head -n1

echo 'int main(){}' > dummy.c && g++ -o dummy dummy.c
if [ -x dummy ]
  then echo "g++ compilation OK";
  else echo "g++ compilation failed"; fi
rm -f dummy.c dummy
EOF
bash version-check.sh

额外，装qemu方便测试，lzip用于ed源代码解包。
1.2创建变量
export LFS=/mnt/lfs
使用如下命令确认变量（一定要在root账户下再确认一遍）
echo $LFS
1.3准备硬盘
这里选用和LFS略有区别的方案，采用的是loop法，这里不做详细介绍。主要是为了方便测试。
dd bs=1G count=60 if=/dev/zero of=60.img #划分60G的img空盘作为虚拟硬盘
sudo cfdisk ~/60.img #dos分区，一个就行
sudo kpartx -av ~/60.img #让img变成系统分区
mkfs.ext4 /dev/mapper/loop0p1 #格式化，linux内核默认兼容ext4，这里请切换为su，后续将维持在su下，ubuntu可能为loop3，自行用lsblk确认下
1.4挂载分区
mkdir -pv $LFS
mount -v -t ext4 /dev/mapper/loop0p1 $LFS
请使用lsblk确认挂载成功
1.5下包
几点说明：①GNU，CPAN镜像用的是上海交通大学镜像，kernel.org为中科大镜像，openssh为清华大学镜像
②内核为opensuse提供的定制的4.19LTS内核
③从LFS中被删除的包：iana-etc, gdbm, gperf, expat, XML::Parser, intltool, libffi, python3(glibc编译需要py3, 但chroot后不安装), ninja, meson, check, kbd, libpipeline, vim, sysklogd, pkg-config, sysvinit, 加入的包：ed, nano, dhcpcd, openssh, wget, pkgconf, openrc
④OpenRC已加入，脚本还需重写
⑤源代码ed是用lzip压缩的，请自行安装lzip，在chroot之前把ed解包，lzip暂不编译
⑥file如果不好下载可以改为https://github.com/file/file/archive/FILE5_37.tar.gz, dhcpcd不好下可以改为https://github.com/rsmarples/dhcpcd/archive/dhcpcd-8.0.6.tar.gz
mkdir -pv $LFS/sources
chmod -v a+wt $LFS/sources #可选，方便非root用户复制源代码包到文件夹
cat > wgetlist << "EOF"

1.9解包说明与编译说明
在sources里面tar xvf（v可以省略）文件夹，cd进去。编译完成，删除解包的文件夹
自行在make后面-jx x为电脑线程数，可以额外+1，gcc，内核等SBU非常大的可以考虑x-1

第三章 构建编译内核依赖以及ssh, dhcp和nano
3.1 准备虚拟内核文件系统
mkdir -pv $LFS/{dev,proc,sys,run}
mknod -m 600 $LFS/dev/console c 5 1
mknod -m 666 $LFS/dev/null c 1 3
mount -v --bind /dev $LFS/dev
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 $LFS/run
3.2 chroot
chroot "$LFS" /tools/bin/env -i \
    HOME=/root                  \
    TERM="$TERM"                \
    PS1='(sure chroot) \u:\w\$ ' \
    PATH=/bin:/usr/bin:/sbin:/usr/sbin:/tools/bin \
    /tools/bin/bash --login +h
3.3 创建目录（几个lib文件夹请确认下，是否要改lib64或者添加lib64）
mkdir -p /{bin,boot,etc/{opt,sysconfig},home,lib64/firmware,mnt,opt}
mkdir -p /{media/{floppy,cdrom},sbin,srv,var}

ln -sf /run /var/run

mkdir -p /var/{opt,cache,lib64/{color,misc,locate},local}
3.4 创建必要的文件和符号链接（几个lib文件夹请确认下，是否要改lib64或者添加lib64）
