重新制作initrd.img
光盘initrd.img
目前光盘引导中的initrd.img为正常安装的700版本系统中的/boot/initrd.img-2.6.32.700-Rocky4.2-x86_64文件重命名
md5=3596a5ee6924547e4c19487039939693
initrd解压
gunzip -S .img initrd.img
cpio -vimd <initrd
initrd修改
1. 解压后目录结构

drwxr-xr-x 6 root root 4096 5月 23 08:08 scripts
2. 在bin目录添加list-devices脚本(该脚本来自于4.2 initrd)
3. 修改scripts下的local文件

### 制作efi 启动文件
#### 制作用于光盘启动bootx64.efi
##### 1. 在4.2系统中grub-2.02-beta2/grub-core目录下制作用于光盘启动bootx64.efi
编写grub.cfg文件，用于初始化efi中的环境变量和找到根引导/boot/grub/x86_64-efi/grub.cfg文件
早期引导的grub.cfg文件如下
search --file /tag --set=root set prefix=($root)/boot/grub/x86_64-efi/ configfile $prefix/grub.cfg
制作bootx64.efi文件
../grub-mkimage --config=grub.cfg -O x86_64-efi -d . -o bootx64.efi -p /boot/grub/x86_64-efi part_gpt part_msdos disk fat exfat ext2 ntfs xfs appleldr hfs iso9660 normal search_fs_file configfile linux linux16 chain loopback echo efi_gop efi_uga video_bochs video_cirrus file gfxmenu gfxterm gfxterm_background gfxterm_menu halt reboot help jpeg ls png true
##### 2. 拷贝efi所依赖的模块到x86_64-efi目录
mkdir x86_64-efi cp *.mod *.lst x86_64-efi/
##### 3. 在x86_64-efi目录下编写镜像启动的grub.cfg文件
set default="0"
insmod efi_gop insmod efi_uga insmod part_gpt insmod ext2 insmod gettext set root=(hd0) search --file /tag --set=root set timeout=5
END /etc/grub.d/00_header

##### 4. 在8.0系统下制作bootx64.img
dd if=/dev/zero of=bootx64.img bs=1M count=20 mkfs.vfat bootx64.img mount bootx64.img /mnt -o loop mkdir -p /mnt/efi/boot/ cp bootx64.efi /mnt/efi/boot/ umount /mnt cp bootx64.img cd2/boot/grub/ cp -r x86_64-efi cd2/boot/grub/
#### 制作用于系统启动的bootx64.efi
##### 1. 在4.2系统中grub-2.02-beta2/grub-core目录下制作用于系统启动的bootx64.efi
制作bootx64.efi文件
../grub-mkimage -O x86_64-efi -d . -o bootx64.efi -p /efi/boot/x86_64-efi search_fs_file search_fs_uuid search_label search part_gpt part_msdos disk fat exfat ext2 ntfs xfs appleldr hfs iso9660 normal search_fs_file configfile linux linux16 chain loopback echo efi_gop efi_uga video_bochs video_cirrus file gfxmenu gfxterm gfxterm_background gfxterm_menu halt reboot help jpeg ls png true
##### 2. 将bootx64.efi添加到光盘环境
mkdir cd2/opt/efi/boot -p cp bootx64.efi x86_64-efi/ -r cd2/opt/efi/boot/
------------------------------------------------------------------------------
### 添加efi自动安装脚本
#### 1.编写efi安装脚本
创建cd2/usr/lib/new_install/operation/finish_install/99exec_install_efi.sh
#!/bin/bash
efimode=cat /proc/cmdline | sed 's/.*efimode=\([^ ]*\).*/\1/'
upgrubcmd="/usr/sbin/update-grub"
if [ $efimode == "y" ];then
source ./functions
efi_dir="/opt/efi/boot"
mkdir -p $TARGET/boot/efi/efi/boot
cp ${efi_dir}/bootx64.efi $TARGET/boot/efi/efi/boot/
cp -r ${efi_dir}/x86_64-efi $TARGET/boot/efi/efi/boot/
cp $TARGET/boot/grub/grub.cfg $TARGET/boot/efi/efi/boot/x86_64-efi/
echo 'exec grub-mkconfig -o /boot/efi/efi/boot/x86_64-efi/grub.cfg $@ ' > $TARGET/$upgrubcmd
echo -e "Install efi successfully !" else echo -e "not efi mode !" fi
#### 2.增加对efi分区情况的限制
