linux.1, linux.2 (bootstrap, vmlinuz and initrd)
2. Client machine using PXE client, downloads the bootstrap (linux.0),
which then downloads linux.1 & linux.2.
3. Linux.1 (vmlinuz) decompresses and tris to mount root fs
4. Error: "VFS: cannot open root device "" or 01:01"
"Please append a correct "root=" boot option"
