I'm not using init, I'm running my script as init. So I'd guess it's
using /dev/console, yes.
I know that /dev/console is funky. That's why I want the option to let ctrl-c
kill the whole vmlinux instance. (Possibly as a command line option.) I'll
look into that later...

Host is swapping, client configured without even support for swap. (If I can
get the darn client vmlinux down to 1 megabyte, I'd be thrilled. Didn't
somebody once make the entire block layer configurable out once? With
hostfs, I don't need it...)
