+Note: In order to use the **size** option for quota on *overlay* storage you must use the *xfs* file system. The mount point that the *overlay* file system must be setup with the *pquota* flag at mount time. If you are setting up / to be used with quota, you have to modify the linux boot line in /etc/grubq2.conf and add the rootflags=pquota flag.
