os-prober is a seperate package. It has nothing to do with us, except
that we call it to generate menuentries, if it's avaible.
It takes the root= value for the Linux kernel out of lilo.conf, menu.lst
or grub.cfg depending what you have on that partition installed.
So you have to change the bootloader configuration of your Debian etch.
