## This script updates the 'limit-set' xattr on the newly added node. Please
## refer hook-scripts/add-brick/pre/S28Quota-root-xattr-heal.sh for the complete
## description.
## Do the following only if limit configured on root.
## 1. Do an auxiliary mount.
## 2. Get 'limit-set' xattr on root
## 3. Set xattrs with the same value on the root.
## 4. Disable itself
