Re: Bug#461442: please add support for os-prober to detect other OSes in update-grub

You could try with qemu.
Update:
I tried with Knoppix on a computer that has Debian sid and Windows XP
installed. The attached script did it's job well - of course except for
the part when it has to convert Linux device names to GRUB drives (see
#462218). Support for HURD is still outstanding, though.
Cheers,
Fabian
