   8 # This script idealy goes into /usr/local/bin and is called update-fstab -
   9 # you need to configure your fstab entries in separate files in /etc/fstab.d;
  10 # only filenames starting with two digits are included!
  11 # Examples: /etc/fstab.d/01base or /etc/fstab.d/61nfs-dm8000, to name just two.
