I now had time to test sinit. I first had trouble getting the FIFO
to work. When booting with the root fs mounted read-only, the child
dealing with the FIFO would segfault. When booting with my root fs
mounted read-write my rcinitcmd would become a zombe since the FIFO code
never reaps children.

So I changed spawn() to wait for its child. Now I can mount my root fs
read-write in my rcinitcmd or even setup a tmpfs, and my rcinitcmd will
have its exit status checked and not become a zombie. This means though
that you can't use the FIFO until the rcinitcmd exited (which means
you might want to chane your rc.svc to background the agetty loop).

Also, would it be worth it to deal with x86 Linux's ctrl-alt-del? It would
pull in OS specific code, and maybe people don't care for ctrl-alt-del
on the console, since everybody lives in X anyway.
