似乎没有完全走通，不过没关系，这个的确是有趣的想法，一个介于 -kernel 直接启动内核和 edk2 之间的方案:

WARNING: Image format was not specified for '/home/martins3/data/hack/vm/fedora-firecracker/img/boot1' and probing guessed raw.
         Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted.
         Specify the 'raw' format explicitly to remove the restrictions.
