LFS 10.0 zero-based Chinese installation tutorial super detailed (4)

                                   第四章  配置系统让系统可以启动

1. LFS-boot script

cd /sources
tar xvf lfs-bootscripts-20200818.tar.xz
cd lfs-bootscripts-20200818
make install
cd ..
rm -rf lfs-bootscripts-20200818

2. Create custom udev rules:

bash /lib/udev/init-net-rules.sh
cat /etc/udev/rules.d/70-persistent-net.rules

3. Create a network configuration file:

cd /etc/sysconfig/
cat > ifconfig.enp0s3 << "EOF"
ONBOOT=yes
IFACE=enp0s3
SERVICE=ipv4-static
IP=192.168.3.27
GATEWAY=192.168.3.1
PREFIX=24
BROADCAST=192.168.3.255
EOF

Configure the network file according to your actual configuration here. It is the first chapter, tell me the name of the network card, IP address and so on.
4. Create the /etc/resolv.conf file:

cat > /etc/resolv.conf << "EOF"
# Begin /etc/resolv.conf

domain mylfs10.0
nameserver 192.168.3.1

# End /etc/resolv.conf
EOF

5. Configure the system host name:

echo "lfs10.0"  > /etc/hostname

6. Create the /etc/hosts file:

cat > /etc/hosts << "EOF"
# Begin /etc/hosts

127.0.0.1 localhost
192.168.3.20 lfs10.0 

# End /etc/hosts
EOF

7. Create the /etc/inittab file:

cat > /etc/inittab << "EOF"
# Begin /etc/inittab

id:3:initdefault:

si::sysinit:/etc/rc.d/init.d/rc S

l0:0:wait:/etc/rc.d/init.d/rc 0
l1:S1:wait:/etc/rc.d/init.d/rc 1
l2:2:wait:/etc/rc.d/init.d/rc 2
l3:3:wait:/etc/rc.d/init.d/rc 3
l4:4:wait:/etc/rc.d/init.d/rc 4
l5:5:wait:/etc/rc.d/init.d/rc 5
l6:6:wait:/etc/rc.d/init.d/rc 6

ca:12345:ctrlaltdel:/sbin/shutdown -t1 -a -r now

su:S016:once:/sbin/sulogin

1:2345:respawn:/sbin/agetty --noclear tty1 9600
2:2345:respawn:/sbin/agetty tty2 9600
3:2345:respawn:/sbin/agetty tty3 9600
4:2345:respawn:/sbin/agetty tty4 9600
5:2345:respawn:/sbin/agetty tty5 9600
6:2345:respawn:/sbin/agetty tty6 9600

# End /etc/inittab
EOF

8. Create the /etc/sysconfig/clock file:

cat > /etc/sysconfig/clock << "EOF"
# Begin /etc/sysconfig/clock

UTC=1

# Set this to any options you might need to give to hwclock,
# such as machine hardware clock type for Alphas.
CLOCKPARAMS=

# End /etc/sysconfig/clock
EOF

9. Configure the console language environment and create the /etc/profile file:

cat > /etc/locale.conf << "EOF"

LANG=en_US.UTF-8

EOF

cat > /etc/profile << "EOF"
# Begin /etc/profile

export LANG=en_US.UTF-8

# End /etc/profile
EOF

10. Create /etc/inputrc file:

cat > /etc/inputrc << "EOF"
# Begin /etc/inputrc
# Modified by Chris Lynn <[email protected]>

# Allow the command prompt to wrap to the next line
set horizontal-scroll-mode Off

# Enable 8bit input
set meta-flag On
set input-meta On

# Turns off 8th bit stripping
set convert-meta Off

# Keep the 8th bit for display
set output-meta On

# none, visible or audible
set bell-style none

# All of the following map the escape sequence of the value
# contained in the 1st argument to the readline specific functions
"\eOd": backward-word
"\eOc": forward-word

# for linux console
"\e[1~": beginning-of-line
"\e[4~": end-of-line
"\e[5~": beginning-of-history
"\e[6~": end-of-history
"\e[3~": delete-char
"\e[2~": quoted-insert

# for xterm
"\eOH": beginning-of-line
"\eOF": end-of-line

# for Konsole
"\e[H": beginning-of-line
"\e[F": end-of-line

# End /etc/inputrc
EOF

11. Create /etc/shells file

cat > /etc/shells << "EOF"
# Begin /etc/shells

/bin/sh
/bin/bash

# End /etc/shells
EOF

12. Create the /etc/fstab file:

cat > /etc/fstab << "EOF"
# Begin /etc/fstab

# file system  mount-point  type     options             dump  fsck
#                                                              order

/dev/sda2     /            ext4    defaults            1     1
/dev/sda1     swap         swap     pri=1               0     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
EOF

Here you need to change <XXX> (system boot disk), <yyy> (system swap partition), and <fff> (boot disk partition format).

13. Configure, compile and install the linux5.8.3 kernel:

cd /sources
tar xvf linux-5.8.3.tar.xz
cd linux-5.8.3
make mrproper
make defconfig
make menuconfig

Make sure of the following options:

Device Drivers  --->
  Generic Driver Options  --->
   [ ] Support for uevent helper [CONFIG_UEVENT_HELPER]
   [*] Maintain a devtmpfs filesystem to mount at /dev [CONFIG_DEVTMPFS]

Processor type and features  --->
   [*]   EFI stub support  [CONFIG_EFI_STUB]

General setup -->
   [*] Control Group support [CONFIG_CGROUPS]

After configuration, save and exit.
Compile the kernel image and modules and install:

make
make modules_install

Move the kernel image to /boot (x86 architecture):

cp -iv arch/x86/boot/bzImage /boot/vmlinuz-5.8.3-lfs-10.0

The symbol file of the kernel:

cp -iv System.map /boot/System.map-5.8.3

Documentation for installing the Linux kernel:

install -d /usr/share/doc/linux-5.8.3
cp -r Documentation/* /usr/share/doc/linux-5.8.3

Create the /etc/modprobe.d/usb.conf file:

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

14. Set up the GRUB boot process.
Install the GRUB file to /boot/grub and set the boot sector:

grub-install /dev/sda

Create the /boot/grub/grub.cfg file:

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 5.8.3-lfs-10.0" {
        linux   /boot/vmlinuz-5.8.3-lfs-10.0 root=/dev/sda2 ro
}
EOF

15. Create the /etc/lfs-release file:

echo 10.0 > /etc/lfs-release

16. Create the /etc/lsb-release file:

cat > /etc/lsb-release << "EOF"
DISTRIB_ID="Linux From Scratch"
DISTRIB_RELEASE="10.0"
DISTRIB_CODENAME="<your name here>"
DISTRIB_DESCRIPTION="Linux From Scratch"
EOF

17. Create the /etc/os-release file:

cat > /etc/os-release << "EOF"
NAME="Linux From Scratch"
VERSION="10.0"
ID=lfs
PRETTY_NAME="Linux From Scratch 10.0"
VERSION_CODENAME="<your name here>"
EOF

18. The last step is to restart the system and
exit the chroot environment:

logout

Unmount the virtual file system:

umount -v $LFS/dev/pts
umount -v $LFS/dev
umount -v $LFS/run
umount -v $LFS/proc
umount -v $LFS/sys

Unmount the primary partition:

umount -v $LFS

Reboot the system:

shutdown -r now

Next, Blfs struggles!
I hope everyone can criticize and correct the shortcomings!
Thank you for watching~! ~
