Public bug reported:
I am installing an Ubuntu system with two disks attached; I want the
OS to be installed on the second disk /dev/sdb; the first disk
/dev/sda is currently completely empty (not even partitioned). The
install process works fine, but then GRUB ignores the line:
d-i grub-installer/bootdev string /dev/sdb
and complains that it cannot write to /dev/sda (because it does not
even have a partition table).
Same happens if I use GRUB's own notation "(hd1)" instead of /dev/sdb
in the preseed file.
If I omit the "grub-installer/bootdev" line in the preseed, then D-I
stops to ask me if I want to install GRUB on sda or sdb.
The issue can be replicated with virtual machines: add two disks (one
of the empty / zeroed out), and instruct the preseed to install on the
second one.
I think this is the same as Debian bug #666974, but I'm filing it
separately as I'm not sure what/how much is changed in Ubuntu's
version of D-I. See: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=666974
