rocky6.0.42.41-x86_64-security-20181101-700.iso
一、重新制作initrd.img
1.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
2.initrd解压
gunzip -S .img initrd.img
cpio -vimd <initrd
3.initrd修改
（1） 解压后目录结构
root@Linx:/tmp/c# ls -l
总用量 31732
drwxr-xr-x 2 root root 4096 5月 23 08:08 bin
drwxr-xr-x 3 root root 4096 5月 23 08:08 conf
drwxr-xr-x 6 root root 4096 5月 23 08:08 etc
-rwxr-xr-x 1 root root 6008 9月 12 2018 init
-rw-r--r-- 1 root root 32417792 5月 23 08:04 initrd
drwxr-xr-x 5 root root 4096 5月 23 08:08 lib

drwxr-xr-x 2 root root 4096 5月 23 08:08 sbin
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)

4.initrd压缩
find . | cpio -o -H newc | gzip -9 > ../initrd.img
二、制作镜像
1.解压镜像
mount rocky6.0.42.41-x86_64-security-20181101-700.iso /mnt -o loop
mkdir cd2
cp -Ra /mnt/. ./cd2
2.替换initrd
cp initrd.img ~/cd2/boot/
3.添加分区对vfat的支持
（1）修改cd2/usr/lib/new_install/new_partition/interface_partition.py文件
--- /root/cd2/usr/lib/new_install/new_partition/interface_partition.py 2018-10-30 05:30:13.000000000 +0000

for fs in list_fs:
lb_fstype.append(fs, fs)
lb_fstype.setCurrent('ext3')
（2）修改/root/cd2/usr/lib/new_install/text/ri_newt.py

Screen.widget_listbox(3, *fs_list)
Screen.widget_checkbox('Format the partition')
Screen.listbox.setCurrent('ext3')
三、制作efi 启动文件
1.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(为解决某些机器,如c30，不能自动加载grub.cfg问题)
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 ###
menuentry 'Manu Install Rocky OS 4.2' --class rocky --class gnu-linux --class gnu --class os {
insmod part_gpt
insmod fat
linux /boot/isolinux/vmlinuzI instmode=Text efimode=y root=/dev/cdrom vga=791 ro
initrd /boot/isolinux/initrd.img
}
menuentry 'Auto Install Rocky OS 4.2' --class rocky --class gnu-linux --class gnu --class os {
insmod part_gpt

initrd /boot/isolinux/initrd.img
}
menuentry 'StateGrid AutoInstall Rocky OS 4.2' --class rocky --class gnu-linux --class gnu --class os {
insmod part_gpt
insmod fat
linux /boot/isolinux/vmlinuzI instmode=StateGrid efimode=y root=/dev/cdrom vga=791 ro
initrd /boot/isolinux/initrd.img
}
menuentry 'Dmraid Install Rocky OS 4.2' --class rocky --class gnu-linux --class gnu --class os {
insmod part_gpt
insmod fat
linux /boot/isolinux/vmlinuzI instmode=Dmraid efimode=y dmraid=true root=/dev/cdrom vga=791 ro
initrd /boot/isolinux/initrd.img
}
（4） 在8.0系统下制作efi.img
dd if=/dev/zero of=bootx64.img bs=1M count=20
mkfs.vfat efi.img
mount efi.img /mnt -o loop
mkdir -p /mnt/efi/boot/
cp bootx64.efi /mnt/efi/boot/
umount /mnt
cp efi.img cd2/boot/grub/
cp -r x86_64-efi cd2/boot/grub/
2.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/
三、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="/Rocky/boot-efi"
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
sed -i 's/\/boot\/grub\/grub.cfg/\/boot\/efi\/efi\/boot\/x86_64-efi\/grub.cfg/' $TARGET/$upgrubcmd
ln -snf /boot/efi/efi/boot/x86_64-efi/grub.cfg $TARGET/boot/grub/grub.cfg
echo -e "Install efi successfully !"
else
echo -e "not efi mode !"
fi
2.增加对efi分区情况的限制
更改/cd2/usr/lib/new_install/text/ri_newt.py

四、制作镜像
1.安装isolinux
apt-get install isolinux
2.mk_iso_4.2.sh脚本
#!/bin/bash
# shiftwidth=4 tabstop=4
isopath="$1"
output="$2"
xorriso -as mkisofs -r -checksum_algorithm_iso md5,sha1 -V `cat ${isopath}/tag| cut -b1-32` -o ${output} -J -isohybrid-mbr /usr/lib/ISOLINUX/isohdpfx.bin -partition_offset 16 -J -cache-inodes -b boot/isolinux/isolinux.bin -c boot/isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -eltorito-alt-boot -e boot/grub/efi.img -no-emul-boot -isohybrid-gpt-basdat -isohybrid-apm-hfsplus $isopath
3.执行脚本制作镜像
./mk_iso_4.2.sh cd2 linx4.2-700-uefi.iso
五、集成到自动编译工具
1. 需要修改的库和文件
修改new_install(根据上方叙述进行修改）
１．修改new_install/new_partition/interface_partition.py文件
２．修改new_install/text/ri_newt.py文件
３．添加new_install/operation/finish_install/99exec_install_efi.sh文件
修改autobuild-tools
1.添加autobuild-tools/integration-tool/cfg/iso_env/x86_64/cfg/boot/grub/grub.cfg
2.添加autobuild-tools/integration-tool/cfg/iso_env/x86_64/cfg/boot/grub/x86_64-efi
3.添加autobuild-tools/integration-tool/cfg/iso_env/x86_64/cfg/boot/grub/efi.img
4.添加autobuild-tools/integration-tool/cfg/iso_env/x86_64/cfg/boot/grub/bootx64.efi
5.修改autobuild-tools/integration-tool/mk_iso
438 echo "info: 安装uefi引导文件"

更更改为如下命令，可以编过。
xorriso -as genisoimage -r -checksum_algorithm_iso md5,sha1 -V `cat ${isopath}/tag| cut -b1-32` -o ${output} -J -isohybrid-mbr /usr/share/syslinux/isohdpfx.bin -partition_offset 16 -J -cache-inodes -b boot/isolinux/isolinux.bin -c boot/isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -eltorito-alt-boot -b boot/grub/efi.img -no-emul-boot $isopath
修改x11-driver
xf86-video-fbdev-0.4.2.tar.bz2 将编译的fbdev_drv.so放到usr/lib64/xorg/modules/drivers/下 并修改/etc/X11/xorg.config /将vesa改为fbdev
为保证图形界面正常，在重新编译x11-driver使其支持fbdev 更改x11-driver编译文件Pkgfile
在drivermoduledir参数里添加xf86-video-fbdev-0.4.2
尝试编译时出现报错，部分/usr/lib/下的库不对，将不对的库删除可以编过，或更改符号链接，链接到/usr/lib64下的相应库也可编过。
尝试使用同一个grub.config
在grub-2.02-beta2/grub-core目录下 修改bootx64.efi文件
search --file /tag --set=root
set prefix=($root)/boot/grub/x86_64-efi
configfile $prefix/grub.cfg
修改grub.cfg
../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
修改new_install/operation/finish_install/99exec_install_efi.sh文件
上述尝试失败，重做bootx64.efi后依然无法找到/boot/grub/grub.cfg文件，调查可能是由于efi启动文件有格式要求，现在的方式是在99exec_install_efi.sh文件中插入一条,建立软链接/boot/grub/grub.cfg链接到启动文件。
ln -snf /boot/efi/efi/boot/x86_64-efi/grub.cfg $TARGET/boot/grub/grub.cfg
去除/ope文件夹
在Rocky目录下创建boot-efi文件,将bootx64.efi和x86_64-efi文件放到/Rocky/boot-efi目录下。 修改99exec_install_efi.sh文件使其从/Rocky/boot-efi安装文件。
更改安装目录efi_dir="/Rocky/boot-efi"
