Setting GRUB_TIMEOUT=-1 has the effect you're asking for, with no need
to change the existing grub.d scripts.  (You'll still get a timeout line
in grub.cfg, but that's OK.)

This was indeed entirely undocumented.  Rather than sprinkling lots of
documentation through /etc/default/grub and annoying people with
conffile change prompts, it seemed much better to flesh out 'info grub'
to document the available keys in /etc/default/grub in detail, so that's
what I've done upstream.  The next upload will include this text in the
section on /etc/default/grub in 'info grub', which I will consider to
close this bug:

`GRUB_TIMEOUT'
     Boot the default entry this many seconds after the menu is
     displayed, unless a key is pressed.  The default is `5'.  Set to
     `0' to boot immediately without displaying the menu, or to `-1' to
     wait indefinitely.

Thanks,
