You probably want to look at 'embedded systems' - where Linux is used
on things like a Tivo, or cell phones, or a Zaurus PDA, and so on.  Often
these run very stripped down kernels.  If you know you'll only every have
7 I/O devices, there's no need for any other device drivers, and a lot of
the networking support can often be trimmed down, extra filesystems removed
(when your filesystem is on flash, you may not need anything except ramfs
or jffs2, so heave ext[23]. jfs, reiser, and so on).

Oh, and they often boot with 'init=/the_one_binary' and don't even  bother
with an inittab....
