So after talking to David Sterba there is no way to tell if a given subvolume is for the entire partition. Also my attempt to "fix" it by using the -o option is unreliable. Richard, so what should be done with the root-partition-listed-twice issue mentioned in the URL above? Just check for a plain '@', assume thats the entire thing, and skip it to not set is_root=1?

The other bug is that mounting subvolumes in such setup fails anyway because the subvol= argument lacks the absolute path. It was suggested to use the "subvolume list" option -a and tweak the resulting list. There is a <FS_TREE> prefix, which shouldnt be there according to David.
