Tim, Maybe initrd and linuxrc is enough for your system. Read the file initrd.txt in the Linux source tree Documentation sub-directory.

Yes. You will always have SOME kind of filesystem. But this begs another question. How much do you know about Linux, and what are you really asking?

The /proc filesystem is not really on any disk, just like /dev (I think) isn't on any disk, though they look like to us users that they are filesystems.
