Where is /bin/login started?
So I'm currenly learing sysVinit. I know that at startup /bin/login has to be started in order to display a login prompt but I couldn't find a file that starts it. Is it started by default in terminals specified in inittab or what's going on there?

It is started by getty after the username is input.
Init starts /bin/agetty (or another getty) on each terminal, according to inittab
Getty initializes the terminal, shows /etc/issue and the "login:" prompt- User enters the login name
Getty execs /bin/login with the username as parameter
Login shows the password prompt (internal or from PAM)
(Note: login was also used for remote Telnet logins (although not by ssh logins), and the process was similar: telnetd would show the username prompt, and would start login for password prompt.)
In systemd, the process is nearly the same: init starts agetty according to getty@<tty>.service, and agetty starts login.
