Comment # 3 on bug 980065 from Josef Reidinger

for me it is storage problem, as mount points do not contain "/" which is
problem for bootloader:

mountPoints {"/home"=>["/dev/sda3", 131, "/dev/sda", ""],
"/data-hdd3"=>["/dev/sdb3", 131, "/dev/sdb", ""], "swap"=>[["/dev/sda1", 130,
"/dev/sda", ""]]}
