I don't think this is related to Augeas. Instead, I think it's the naming 
convention SUSE uses for the root btrfs subvolume (@).

I encountered this same issue in virt-v2v and posted a question here: 
https://www.redhat.com/archives/libguestfs/2014-April/msg00071.html

At the time, the problem only seemed to break v2v in SUSE environments, so I 
created a local patch to strip out the duplicate root in the v2v process. As 
other tools are running into this, we should probably deal with this in 
guestfs itself.
