Subject: [PATCH] ctdb-eventscripts: New configuration variable
 CTDB_GANESHA_REC_SUBDIR

Backup and restore of the cluster filesystem can upset the operation
of 60.ganesha by changing the contents of this subdirectory.

Allow this subdirectory to be configured to a subdirectory that is
ignored by backup and restore processes.
