It connects via the kernel via init=, as always. Maybe not the best
choice of words, but the important thing is that the statement about
GRUB2 having its "own init system and it's own set of init scripts" is
false. I noted the "connection" between the bootloader and the init
system (via the init= command line) to emphasize that GRUB2 has not
its own init system. Nor init scripts.
