[PATCH] 30_os-prober: derive --class from os-prober generated label


From: Andrey Borzenkov
Subject: [PATCH] 30_os-prober: derive --class from os-prober generated label
Date: Sat, 26 Dec 2015 10:09:28 +0300

Currently only Windows gets distinguished icons, everything else is displayed
using the same generic one. Add additional --class based on os-prober returned
label, which usually is expected to match primary distribution name.

Also use it for Windows as well - chainloader prober nay actually return
different strings (Windows, MS-DOS, Windows9xME).
