Bug#578338: debian-installer: grub-install fails to md0

[Eric Dantan Rzewnicki <eric@zhevny.com>]

Package: debian-installer
Version: daily-images amd64 netboot.tar.gz 2010-0418
Severity: important


I reported this problem a few weeks ago when attempting to install a very
similar system: http://lists.debian.org/debian-user/2010/04/msg00092.html

This time I again used the daily image (2010-04-18):
http://d-i.debian.org/daily-images/amd64/daily/netboot/netboot.tar.gz

via tftpboot.

The system install works fine up to the point of attempting to install grub:

Apr 19 08:06:09 grub-installer: info: Installing grub on '(hd0)'
Apr 19 08:06:09 grub-installer: info: grub-install supports --no-floppy
Apr 19 08:06:09 grub-installer: info: Running chroot /target grub-install  --no-floppy --force "(hd0)"
Apr 19 08:06:10 grub-installer: /usr/sbin/grub-probe: error: no mapping exists for `md0'.
Apr 19 08:06:10 grub-installer: Auto-detection of a filesystem module failed.
Apr 19 08:06:10 grub-installer: Please specify the module with the option `--modules' explicitly.
Apr 19 08:06:10 grub-installer: error: Running 'grub-install  --no-floppy --force "(hd0)"' failed.

I saved the full hardware-summary, partman and syslog files. Let me know where
to send them. I do not need this system up immediately, so can help with
sorting it out. I am edrz on irc.
