I have the same issue, the install process should use a symbolic link rather then a bind.
My issue with bind is that my cpanel is reporting disk usage on /usr/local when the media lives on a different partition, I used --vhosts=/home/centovav3.
Removing the mount point and creating a sym link, fixes the issue
/usr/local/centovacast/var -> /home/centovav3
Cheers
