Linux 2.6 kernels bundle a small ram-based initial root filesystem
*into the kernel*, and if this filesystem contains a program called
"/init" the kernel runs that as its first program.
Linux kernel already had a way to provide a ram-based root filesystem,
the initrd mechanism. For 2.4 and earlier kernels, initrd is still the
only way to do this sort of thing. But the kernel developers chose to
implement a new mechanism in 2.6 (initramfs). To enable this feature
select pre-build initramds in CONFIG_INITRAMFS_SOURCE.
