We have two services that indicate boot finish. Those are
start-indicator and rainbow. They have start level 99 but these services
have it set as well and thus sometimes start after indicator. The result
is that tests relying on indicator can initially fail because they just
start too early.
It is also a good idea to just not keep 99 level for use like
start-indicator so this moves all services to earlier level rather than
just affected ones.
