1 year ago 以下是我的grub2 的实现 sudo gedit /usr/share/initramfs-tools/hooks/vdfuse
!/bin/sh -e
PREREQ="" prereqs() { echo "$PREREQ" }
case "$1" in prereqs) prereqs exit 0 ;; esac
. /usr/share/initramfs-tools/hook-functions
copy_exec /etc/fuse.conf /etc copy_exec /usr/bin/qemu-nbd /sbin
修改init-top实现自定义文件系统挂载逻辑 sudo gedit /usr/share/initramfs-tools/scripts/init-top/vdfuse
!/bin/sh -e
PREREQ="udev" prereqs() { echo "$PREREQ" }
case "$1" in prereqs) prereqs exit 0 ;; esac
if [ ! -z $vdisk ]; then mkdir /vdhost mkdir /dev/vdhost mount -t ntfs $host /vdhost/ modprobe nbd exec -a @11 /sbin/qemu-nbd -c /dev/nbd1 /vdhost$vdisk mount -t ext4 $ROOT /root
fi
sudo gedit /usr/share/initramfs-tools/scripts/init-bottom/vdhost
!/bin/sh -e
PREREQ="" prereqs() { echo "$PREREQ" } case "$1" in prereqs) prereqs exit 0 ;; esac if [ -d ${rootmnt}/vdhost ]; then mount -n -o move /vdhost ${rootmnt}/vdhost fi
sudo chmod +x /usr/share/initramfs-tools/hooks/vdfuse
sudo chmod +x /usr/share/initramfs-tools/scripts/init-top/vdfuse
sudo chmod +x /usr/share/initramfs-tools/scripts/init-bottom/vdhost
sudo /usr/sbin/mkinitramfs -o ./initrd.img

有尝试其他方案下的动态磁盘引导linux 但是该方案很久没有维护了如果可以希望可以支持到 http://bbs.wuyou.net/forum.php?mod=viewthread&tid=418705&ordertype=1 https://forum.ubuntu.com.cn/viewtopic.php?t=461537
其次有想过 1.将引导部分设置为固定安装最小系统 启动后加载数据 例如(桌面环境或驱动) 2.或者通过加载qemu-nbd 直接引导虚拟系统
