I suppose that this issue depends on implementation of df(1) not unionfs.
Most case df gets filesystem information by getmntinfo(3), but in "df -t"
case, it gets that by statfs(2). "df -t" uses statfs(2) with a target
mount point, so "df -t" prints top layer filesystem information
I guess that to fix this issue, the change of df(1) implementations is
better way :) Do you know who is better man to maintain df(1) implementation?
It seems that df(1) does not have active maintainer.
