Dracut将不会创建包含当前系统未使用的模块的映像。

Question

好的，dracut没有像我所认为的那样表演，我也找不到解决办法。我以前已经创建了几个映像，但现在我正在尝试创建一个实时引导initramfs，以便与自定义的live一起运行。每次我尝试下面的cmdlind参数时，它都会失败，我也尝试将额外的模块放入dracut.conf中，但每次都会发出警告(我在另一个帖子中看到它们只是您可以忽略的警告)，但是在消息返回到终端提示之后，我没有选择忽略或继续使用dracut构建等等。

#dracut.conf short and sweet
add_dracutmodules+="nfs dmsquash-live livenet "
omit_dracutmodules+="biosdevname"

#dracut terminal argument
dracut -v testinitramfs.img 

#output
dracut: Executing: /usr/bin/dracut -v testinitramfs.img
dracut: dracut module 'busybox' will not be installed, because command 'busybox' could not be found!
dracut: dracut module 'btrfs' will not be installed, because command 'btrfs' could not be found!
dracut: dracut module 'dmraid' will not be installed, because command 'dmraid' could not be found!
dracut: dracut module 'dmsquash-live-ntfs' will not be installed, because command 'ntfs-3g' could not be found!
dracut: dracut module 'livenet' depends on 'dmsquash-live', which can't be installed
dracut: dracut module 'stratis' will not be installed, because command 'stratisd-init' could not be found!
dracut: dracut module 'cifs' will not be installed, because command 'mount.cifs' could not be found!
dracut: dracut module 'dmsquash-live' cannot be found or installed.

我已经安装了软件包，我已经安装了dracut.x86 -tools -network -caps -live -squash，我的可用模块列表显示了busybox和dmsquash，但仍然失败，并表示无法找到它们。对于dracut build命令，我还缺少另一个依赖项吗?在这种情况下，我需要更多的依赖项，以使这些模块可以被dracut查看？

我相信您缺少了手册页中的--no-hostonly参数：

  -H, --hostonly        Host-Only mode: Install only what is needed for
                        booting the local host instead of a generic host.
  -N, --no-hostonly     Disables Host-Only mode

另一个常见的问题是缺少模块所依赖的包，例如，在添加device-mapper-multipath模块之前需要使用multipath。
