Bug#514976: grub-probe cannot locate /boot on /dev/sdag1, even when device.map is correct
The affected system here is running debian lenny. I installed the lenny-backports version of bzr and was able to branch. This workaround appears to work for lenny users, as well. Details below. What are the prospects for getting this fixed in stable or oldstable?

Bug#514976: grub-probe cannot locate /boot on /dev/sdag1, even when device.map is correct
I opened #610593 for the very same problem on Squeeze (my system has 41 disks) and I can confirm that both Grub from bzr trunk and Debian Experimental (1.99~rc1-1) fix the problem.
