GRUB timer in Wubi installation is too long

This is due to the fact that grub-installer sets the timeout to 10 seconds if other OSes are discovered. Of course in the Wubi case, menu.lst is used as second boot menu, so that a user has already a chance to change the OS in the first boot menu and hence the 10 seconds delay is not justified in this case. This was discussed briefly on IRC some time ago' but it was decided that special-casing that was probably not worth it.

This bug was fixed in the package grub-installer - 1.35ubuntu2

---------------
grub-installer (1.35ubuntu2) jaunty; urgency=low

  * Hide GRUB menu if grub-installer/bootdev_directory is preseeded; this is
    used in the Wubi case where GRUB is used as a secondary boot loader, and
    so the user already had a chance to boot from another operating system
    (thanks, Agostino Russo; LP: #289791).
  * Use rootnoverify rather than root when chain-loading Microsoft operating
    systems (LP: #10661).
  * 'dmraid -c -s' changed its output format; cope with both old and new.
