My experience has been that upgrading will ask whether you want the new/Debian version of the file. I said no, so it placed that version into a file called grub.ucf-dist. Alternatively, you could echo that line into a file called, say, /etc/default/grub.d/probing.cfg (it's only the .cfg that's important) and that file shouldn't be disturbed by upgrades. Cheers, David.
