Hello,
For the debian installation CD, when using syslinux we can set an
on-timeout entry which is different from the default entry. This is
quite important because we want sighted people to be able to just press
enter to get the sighted installer, and non-sighted people to possibly
just have to wait before getting a self-speaking installer.
Would it be ok to implement this in grub?
How do you inform the user about this arrangement? For sighted people there is expectation that highlighted entry will be booted automatically and also that highlighted entry is booted on enter. It's probably just a UI problem though and it's just a question of correct communication.
