However the default rootfs image is empty, so the kernel will panic when attempting to mount; the user must supply a rootfs if it is required that the kernel completes its boot. No default kernel image is supplied and the config will refuse to run unless it is explicitly specified. Note: If specifying a custom dtb at runtime, this will also override any command line specified at build time, since the command line is added to the chosen node of the default dtb. +A directory can optionally be shared from the host system into the Linux environment running in the FVP.
