Aufs branch of another aufs mount is supported, but it must be readonly.
Since you have enabled CONFIG_AUFS_ROBR, you have read
config AUFS_ROBR
bool "Aufs as an readonly branch of another aufs mount"
help
If you want make your aufs to be a part of another aufs, then
enable this option. In other words, you can specify your aufs
path in 'br:' mount option for another aufs, but cannot
specify 'rw' as the branch permission.
It will have a negative impact to the performance.
See detail in aufs.5.
To be honest, the success of your mount is a bug. I intended to make
"writable aufs branch" rejected.
Additionally I have not tested coda(davfs?) branch...
