/etc/chroot is sadly not as simple as it looks: you have to create
a whole directory tree under /sparedir: it has to contain:

	/sparedir/bin/cpio
	/sparedir/dev/tty	if you run multiple volumes
	/sparedir/dev/rmt0	or whatever, if you run multiple volumes
	/sparedir/bin/mkdir
	/sparedir/shlib/libc_s	for SVR3

at least.  This is tedious and I really hate to bother setting it
up all the time.  Sigh, I wish cpio had an option...
