Bug#653935: please give a possibility to override grub-probe's output

[Marc Haber]

Package: grub-common
Version: 1.99-14g
Severity: wishlist

This is a re-hash of #542165, only in a more general fashion. To call
things back to memory: I don't really boot from my /boot, which is on
a dm-crypt LV, but I unison the hard-disk's /boot to an USB stick
which I then boot from. The hard disk version of the /boot directory
serves as a backup of the USB stick and allows me to update my system
without having to plug in the USB stick.

In this setup, grub-probe fails since it cannot deduce from the
crypted partition to the real device. Please give the possibility to
directly point grub-probe to a device string while turning off its
intelligence.

Greetings
Marc
