This would affect the kernel, won't it?

I am not talking about kernel's output. I am talking about the output from
systemd, telling me that it waits for my script exits.

No. It's on the the way to achieve multi-user.target. This is because I told
that my script is a prerequisite for multi-user.target. So systemd is telling
me that it can't reach multi-user.target because it is waiting for my script
to exit.

It's totally OK that systemd is trying to tell me that. But ist should
restrict its output to some specific VT, instead of polluting every VT as soon
as this VT becomed active.
