I now agree with this :) Modifying /etc/ttys at install time doesn't
work for a lot of cases, LiveCD being the most obvious.

I'd guess that this mode is really a once-off thing - for a live CD,
init could ask the user if they want a getty spawned on this tty similar
to asking for a shell in single-user mode.
Presumably post-install the user would have edited the ttys file and
init would then be able to locate the entry and not have to prompt.
later,
Peter.
