It's not a straight substitution. Oneit runs a single child process
(with a controlling tty), and shuts down the system when that child exits.

You generally run oneit at the end of a PID 1 init script, such as the
one mkroot writes out (lines 171-197):

There is a more conventional system V style init in the pending
directory, but it hasn't gone through the full (time consuming) review
process to be promoted into defconfig yet.
