extras/hook-scripts: Set of changes for new samba share method.
New method of creating a share of gluster volume through samba eliminates the requirement of fuse mount and changes in fstab. glusterfs vfs plugin has to be specified as required vfs object. Path now is relative to the root of gluster volume. / signifies complete volume.

#Need to be copied to hooks/<HOOKS_VER>/start/post
+#TODO: All gluster and samba paths are assumed for fedora like systems.
+#Some efforts are required to make it work on other distros.
+
+#The preferred way of creating a smb share of a gluster volume has changed.
+#The old method was to create a fuse mount of the volume and share the mount
+#point through samba.
+#
+#New method eliminates the requirement of fuse mount and changes in fstab.
+#glusterfs_vfs plugin for samba makes call to libgfapi to access the volume.
+#
+#This hook script automagically creates shares for volume on every volume start
+#event by adding the entries in smb.conf file and sending SIGHUP to samba.
+#
+#In smb.conf:
+#glusterfs vfs plugin has to be specified as required vfs object.
+#Path value is relative to the root of gluster volume;"/" signifies complete
+#volume.
