bootc

https://docs.fedoraproject.org/en-US/bootc/
https://osbuild.org/
https://github.com/osbuild/bootc-image-builder

按照这个操作: https://github.com/osbuild/bootc-image-builder?tab=readme-ov-file#-build-config

是可以走通的

dracut 常用命令

dracut --kver $(uname -r)  --force

initramfs 中应该带什么东西

1. 配置文件

例如介绍在 /etc/modprobe.d/ 中配置 nvme 的 channel ，但是如果 /etc/modprobe.d/ 本身就是存储在 nvme 上，怎么办？ https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/managing_storage_devices/enabling-multipathing-on-nvme-devices_managing-storage-devices

lsinitrd 可以看到:

drwxr-xr-x   2 root     root            0 May 23  2024 etc/modprobe.d
-rw-r--r--   1 root     root          166 May 20  2024 etc/modprobe.d/firewalld-sysctls.conf
-rw-r--r--   1 root     root          674 Feb 18  2023 etc/modprobe.d/tuned.conf

现在可以我知道了

boot 之后，我怎么知道存在 hard disk 的存在
fs 怎么知道自己 mount 到哪一个 partion 上面去

类似的 busybox 的写法

https://github.com/arighi/virtme-ng/blob/main/virtme/mkinitramfs.py

给 ubuntu 或者 debian 打包，也许可以找出什么有用

https://github.com/armbian/build

这里提到的 : mkinitramfs -o ramdisk.img 是什么东西
