Comment 3 for bug 1012629

I've made a bootable USB drive that I am using to start off net installations of a customised ubuntu distro. The trouble is that the USB drive ends up as /dev/sda. Late in the install process the debian installer attempts to install grub to the MBR of /dev/sda despite the whole install going to /dev/sdb.

This will force me to not preseed the grub portion of the install. This is a problem because I am an oem and I need unattended net installs (even if I do need a USB drive to kick the process off due to the bios not having PXE capability).
