We spawn a shell: - When Bash is first built, on tty2. This shell uses the old Bash, so interactive mode needs to be emulated using redirection. Thus, entering commands needs to be done using Enter followed by Ctrl+D, and certain redirection features are unavailable. - After moving the system to disk, on tty2. Old Bash, same limitations. - After 2nd Bash is built, on tty3. This is a fully functional shell. This is disabled in chroot-like bootstrap modes, or when -i is not set.
