Using u-root generate initram.cpio as linux ininrd

u-root contains simple Go versions of many standard Linux tools, similar to busybox. It’s a pure Go userland!
u-root stands for “universal root”. It can create an initramfs.(

And I created a initramfs use bb-mode and run in real x86 pc, it said “no such file or directory” and cannot type anthing into the shell command.
