>Description:
A mount -p should print out the mounted information in a file format usable in /etc/fstab.

When a unionfs is mounted this is not the case; each union mount is prefixed with an <above>:.

>How-To-Repeat:
      Mount union fs, then do mount -p >> /etc/fstab followed by a mount -a to see the errors

>Fix:
      change something inside mount to print it in a complaint format.
