Bug#650414: grub-installer: Change --set to --set=root in 30_otheros

[Brian Potkin <claremont102@gmail.com>]

Package: grub-installer
Severity: minor


I have installed Debian a number of times to a USB stick with today's
daily image from

  http://cdimage.debian.org/cdimage/daily-builds/sid_d-i/current/i386/iso-cd/

An install was done with either no network connection or with the kernel
parameter 'recommends=false'. /etc/grub.d/30_otheros is created with a
typical 'search' line like so:

  search --no-floppy --fs-uuid --set cb83bfa2-57b7-4312-abb1-b0fc2fb7588a

GRUB was installed either to the MBR of the stick or the MBR of /dev/sda.
In both cases, choosing to boot an OS on /dev/sda produces

  error: no argument specified.
	Press any key to continue.

Waiting for 10 seconds or pressing a key allows the boot to proceed.

There is no error message when --set is altered to --set=root in the
line above. --set=root is already in the 'search' line for the OS on the
USB stick and used when os-prober is installed and run from it with
update-grub. Would it not be consistent to have it also in 30_otheros?

The syslog for one install is attached.
