Bug#651512: grub-pc: debconf's 'grub/install_devices' refers to device IDs while debconf shows device names

Package: grub-pc
Version: 1.98+20100804-14+squeeze1
File: /etc/kernel/postinst.d/zz-update-grub
Severity: important
Usertags: pca.it-boot
Hi there!
This could be a duplicate of #650724, but given that the error shown is
different, I reported it as a new bug.
I changed both 500GB Samsung HDs with two 1TB Seagate HDs (in RAID1, LV
for /), in series: changed the first, rebuilt the RAID1, checked that
everything was OK, reconfigured grub-pc for the new disk and then
started again for the second, but it seems I missed the second
'dpkg-reconfigure grub-pc' step and the last kernel upgrade fails:

=====
I think we have two problems here:
1) device.map is not in sync with the current situation, which means
that a simple `grub-mkdevicemap` should solve this.
2) however, debconf's 'grub-pc/install_devices' is not in sync either
and `dpkg-reconfigure grub-pc` does not solve it, while IMHO it
should.
I think there is a fundamental problem here: grub-pc's debconf mixes
device names (/dev/sda) with device IDs (/dev/disk/by-id/...). This
means that while you think you chose device names (so changing disks
should not cause any problem), what is actually used is device IDs,
which are not updated *before* starting grub-probe (so your choice is
not taken into account).
Indeed, updating this line was enough to solve the problem:
