Sure, that is the 'init' program (/sbin/init) which needs to be

kernel, 2. your init). Doubt whether it is really fun ;-)
Thank you everyone for the replies.
I tried this on a full linux distro and ran into trouble. A tutorial on
this would be interesting. How to put together a kernel, bootloader, and
init script or binary (preferably one simple enough you can write
yourself), sorting out the initrd if necessary, statically compiling any
binaries so you can start with an absolute minimum.
Well you theoretically could modify a shell to run without glibc, but
portions of it would need to drop to assembly language to make calls ot
the kernel.
You can read this to give you clues:

Have fun.
