From the init(3) man page on the '-s' flag:

"The functions are executed sequentially in an initialization process, which then terminates normally and passes control to the user. This means that a -s call which does not return will block further processing; to avoid this, use some variant of spawn in such cases."

eunit:test/1 runs to completion, blocking until the tests are done. Therefore, it can't be used directly with the -s flag.
