我在裸机上启动 Tinycore Linux，如下所示：
#!ipxe
# You can test this localy via:
# qemu-img create -f qcow2 mydisk.qcow2 6G
# qemu-system-x86_64 -serial stdio -boot n -m 2000 -hda mydisk.qcow2 -device virtio-net,netdev=n1 -netdev user,id=n1,tftp=$(pwd),bootfile=/tiny-core-linux.ipxe,hostfwd=tcp::2222-:22
# You can ssh into the VM via port 2222.

这在 qemu 上工作正常，但在裸机上失败。
内核恐慌：无法挂载 root fs
你知道如何解决这个问题吗？
