Bug#527604: [grub-common] update-grub fails silently when grub-mkconfig fails on an outdated device.map

I have a system which fails during kernels postinsts because update-grub
returns 1. The problem was located at:
chain)
CHAINROOT=`grub-probe --target=drive --device ${DEVICE} 2
/dev/null`
grub-probe failed because the device.map was outdated. grub-mkconfig
solved the problem.
How could we make sure that the device.map is always up-to-date when
grub-probe is called ?
This bug is important because it blocks kernel upgrades without any
explanation apart from update-grub returns 1 and postinst failed.
update-grub itself returns nothing suspicious at all, since the error
happens after the the last stdout output, does not produce error output
and is only detectable through the exit number.
The error output of grub-probe should probably not be 2 /dev/null or be
somehow parsed.
Cheers

Hi, with the curent squeeze/sid version this shouldn't happen anymore,
prepare_grub_to_access_device is now used in 30_os-prober, which
doestn't send the output of grub-probe to /dev/null.
Though only in the sid version CHAINROOT is completely removed. I forgot
to do this first.
