在挂ext4分区前内核先挂了个uInitrd ramdisk, 我如何查看这个ramdisk的内容呢？
第一步：去掉mkimage加入的64bytes头部。
第二步：接下来由于不知道ramdisk用了何种格式和体积压缩不知道怎么进行下去，请问要如何做呢？
i have figured out that it is a lz4 compress ramdisk throgh the initrd file magic. but how could i mount this 24MB(after lz4 decompress) ramdisk? what is the ramdisk file system type?
i have figured this lz4 uncompress file is cpio format, so the question is solved! thanks.
