and here's fstab, unmodified from install except for the addition of the parameters related to quota:
Code:

# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name
# devices that works even if disks are added and removed. See fstab(5).
