+# To set file permissions is a PITA since git won't save them and will
+# complain heavily if they are set to root only read, so this is the procdure:
+#
+# 1. Change to the directory that you want to have file permissions retained
+# 2. Change all the file permissions / ownership as you want
+# 3. Change back to the root of the exta directory (IE: extra-qubes-files)
+# 4. getfacl -R . > ".facl"
+# 5. If git complains; reset file ownership back to user.  The .facl file stored
+#    the file permissions and will be used to reset the file permissions after
