¶LFS系统构建05-制作LFS系统引导

¶创建fstab文件

# Begin /etc/fstab
# file  system  mount-point     type            options         dump    fsck
#                                                                       order
/dev/sdb        /               ext4            defaults                1 1
/dev/sda4       swap            swap            pri=                    1 0
proc            /proc           proc            nosuid,noexec,nodev     0 0
sysfs           /sys            sysfs           nosuid,noexec,nodev     0 0
devpts          /dev/pts        devpts          gid=5,mode=620          0 0
tmpfs           /run            tmpfs           defaults                0 0
devtmpfs        /dev            devtmpfs        mode=0755,nosuid        0 0
# End /etc/fstab

¶linux内核

#安装内核
cd $LFS/sources/
tar xvf linux-4.20.12.tar.xz
make mrproper
#启用x86默认内核配置
make x86_64_defconfig
#在以上基础上自定义配置
make menuconfig
make
make modules_install
cp -iv arch/x86_64/boot/bzImage /boot/vmlinuz-4.20.12-lfs-8.4
cp -iv System.map /boot/System.map-4.20.12
cp -iv .config /boot/config-4.20.12
install -d /usr/share/doc/linux-4.20.12
cp -r Documentation/* /usr/share/doc/linux-4.20.12

#配置模块加载顺序
install -v -m755 -d /etc/modprobe.d

cat > /etc/modprobe.d/usb.conf << "EOF"
# Begin /etc/modprobe.d/usb.conf


install ohci_hcd /sbin/modprobe ehci_hcd ; /sbin/modprobe -i ohci_hcd ; true
install uhci_hcd /sbin/modprobe ehci_hcd ; /sbin/modprobe -i uhci_hcd ; true

# End /etc/modprobe.d/usb.conf

EOF

¶用grub设置引导进程

cd /tmp
grub-mkrescue --output=grub-img.iso
#需要安装xorriso
wget https://mirrors.ustc.edu.cn/gnu/xorriso/xorriso-1.3.0.tar.gz 
tar -zxvf xorriso-1.3.0.tar.gz
cd xorriso-1.3.0
./configure --prefix=/usr
make
make install 
xorriso -as cdrecord -v dev=/dev/cdrw blank=as_needed grub-img.iso

#将配置文件写入(如果没有目录则自己创建)
cat > /boot/grub/grub.cfg << "EOF"
# Begin /boot/grub/grub.cfg

set default=0
set timeout=5
insmod ext2
set root=(hd0,2)
menuentry "GNU/Linux, Linux 4.20.12-lfs-8.4" {
linux
/boot/vmlinuz-4.20.12-lfs-8.4 root=/dev/sda2 ro
}
EOF

¶结束

echo "rack-leen-1.0-version" > /etc/rack-leen-release
cat > /etc/lsb-release << "EOF"
DISTRIB_ID="rack-leen"
DISTRIB_RELEASE="1.0"
DISTRIB_CODENAME="rack"
DISTRIB_DESCRIPTION="Rack's Linux"
EOF
