Usually you will always want to have some filesystem support. Unix is pretty much build around the idea of mounting some type of root device - so you will usually always find a root directory, most probably also a /dev/ directory in it, etc. There are many ways to build such a system. a NFS based root filesystem is one; another is uising a ramdisk image which is loaded with the kernel from some boot device (flash, network, ...).
