Bug Description
os-prober will not find other ubuntu installs when their root partitons are Btrfs and created by ubiquity. Ubuntu creates subvolumes with the @ for root and @home. os-prober needs to check inside the @ subvolume or there needs to be a symlink to @/boot @/etc which is hackish/not sane otherwise the other already installed ubuntu versions get overwritten or not seen in the grub menu.
